Thumb-sucking at 18 weeks....

By week 18 of your pregnancy, your baby's crown-to-rump length is 5 to 5.5 inches long. Your baby continues to develop fat layers and weighs about 5.25 ounces. Your baby will continue to grow and develop, but the rapid growth will slow down for a little while. You will be able to feel your uterus just below your bellybutton. If you put your fingers sideways to measure, you can feel your uterus about two finger-widths below your bellybutton. At this point of your pregnancy, your uterus is approximately the size of a cantaloupe. Although weight gain varies from woman to woman, your total weight gain at this point should be 10 to 13 pounds.

At this time if you had an ultrasound, heart abnormalities can be detected. If the ultrasound technician detects abnormalities, further ultrasound exams may be ordered to follow the baby's development. There is still space available in your uterus and your baby will be active for periods at a time. Your baby may sit cross legged or turn somersaults.

Around this time, your baby becomes more sensitive to the outside world and shows her presence through powerful kicks and prods. The bones through which sound is passed to the inner ear have hardened and the parts of the brain that receives and processes nerve signals from the ears are developing. This means that your baby can hear now. Your baby will get used to familiar sounds, such as your heart beating, familiar voices, blood rushing through the umbilical cord and other daily routine sounds. Your baby will become startled if he hears a loud sound.

If you have a stethoscope at home, you can now hear the baby's heartbeat yourself.

Week 18 has arrived. I've been on vacation in the mountains this last week...the altitude definitely got to me while I was there, but it was still nice to get away. The 14 hour drive was horrendous!

Well I'm 18wk 2days, I have only felt the baby move once, that was last week. Seems strange as my other ones were constant movers. I'm already so uncomfortable with everything stretching and growing, I truly do not enjoy my pregnancies lol. Can't wait for the delivery time to be here and over with.

19 weeks tomorrow! Anatomy scan is scheduled for Thursday. Super excited. We are going to find out what we are having but will not be letting anyone know until 4th of July. We are going to have a surprise gender reveal cake.

nycnaz23 - 64 days ago
Hello mommies, Im 18wks as of tomorrow. Is anyone feeling extreme movements? I am feeling it in all the different directions. Going for a full anatomy scan on Tuesday ... DH is going with me for the first time :) im excited. I am able to eat whatever now but i am drained ... totally drained. Hope everyone is well!!

madelynsmom *pink* - 65 days ago
gender scan tomorrow! super excited!

mommashavin11 - 65 days ago
so excited , scan in 6 days, but not sure if were finding our gender! i think ill have them put it in a sealed envelope. I have 6 girls, 4 boys, so all my kids hoping for a boy. my youngest boy is 5. i think boy 75% and girl 25 % ...just a hunch! im always wrong though!

SarahMVR - 77 days ago
Anyone else keeping baby a surprise? I keep having girl dreams. They're so vivid too.

monkeymomma - 88 days ago
Sad day saturday....I had to take off my wedding rings because of swelling. I feel so funny without them!

monkeymomma - 94 days ago
Hello 18wks!!! Another week closer to my gender scan!!!!

happythirdbaby - 102 days ago
Congrats Paula! I am also due Oct 14 but was 2 weeks early and 1 week early with my other two children. My scan isn't for another couple of weeks. Such exciting times....

paulasoon2b8 - 104 days ago
Well they changed my date to Oct. 14 but I'm staying here cause baby will be taken before both dates I'm sure....last lil one was induced at 38 and was 9.5 lbs. This lil one length wise matches up to 18 weeks but is up to about 9oz weight...pretty good! Tech wouldn't co.firm girl but showed me the pictures she got and I'm pretty sure it's a girl once results are in to doctor they are allowed to confirm boy or girl...Will start to see OB after this month....and I'm sure he 'll send me for another scan with his techs at the hospital. My prediction is between the 1st and 5th of October I will be having this little bundle

PaulaSoon2B8 - 105 days ago
My cold has left me deaf in one ear...quite literally I cant hear at all!! Its weird :( I am sure the cold is whats keeping me down and tired...I am sure it will get better soon. I cant complain the last 7 pregnancies were amazing to me...this one is just going out with a bang being that its our last :) its all worth it anyways right!!!

happythirdbaby - 106 days ago
Good luck and have fun at the scan today Paula. Hope you feel better and less tired for it too! Is everyone finding out what gender they're having. Gosh I am getting quite nervous about it. I have 2 girls and thought i didn't mind as the girls get along so well, but I guess I do, especially as this is my final pregnancy. I wish we could have a little more control over this lol x

TaraR - 106 days ago
Oh no, Paula! I hope you get to feeling better SOON!!! I'm actually feeling so much better today! :)

PaulaSoon2B8 - 106 days ago
Tara I know exactly how you are feeling!! I can't keep up with everything...ive been battling a horrible sinus cold as well....but I am just exhausted beyond words :( I hope it gets better for you!!!

TaraR - 107 days ago
Just wanted to stop in and say hi!! I'm battling the tiredness again this week. I feel like I need to go to be at 6pm but my 8 and 4 year old don't agree with that! LOL Can't believe we are almost 1/2 way done!! Hope everyone is feeling good!

PaulaSoon2B8 - 108 days ago
Arggg....I was caught up with morning sickness today...hope this isn't the beginning of a new trend in the pregnancy!! I know first and last trimester can be normal...but pregnancy is so different...this one has been trying and testing that for sure...she is making herself memorable!! Anatomy scan this Friday...anyone else have one coming up...this is so exciting....#8 and it's like the 1st all over :)

PaulaSoon2B8 - 109 days ago
Happy Mother's Day to All (belated) Here we are closer and closer to the half way mark!!! Lots of scans and appointments going on I'm sure. We have our anatomy scan this Friday, hoping to confirm that she really is a she so I can start addressing her by name in there :) Hows everyone feeling all in all? I still have constant headaches, fluctuating nausea, motion sickness...and I guess 7 kids, full-time work and pregnancy combined may do that to a girl..Hope you are all well...have great week!!

kekea - 111 days ago
Have a great mothers day guys !!! And 1morefor4 can't wait to know what you having...

1morefor4 - 112 days ago
I just have to get through this weekend and then I will be seeing my little one on Monday (the day I turn 19 weeks). Of course, I'll be doing a blog update after. But, I'm over the moon excited right now because last night for the first time this pregnancy DH felt the baby kick.

RowdyRandi - 112 days ago
I am getting so anxious about my 20 week scan. I wanna know gender so bad i hope baby cooperates. I also wanna know how growth is going my dd was small so wondering how big this one is so far

TaraR - 112 days ago
Happy 18 weeks everyone!! My sweet little mister is getting more active every day. I can't feel him from the outside though but he sure is fluttering around in there! :) I hope everyone is having a great day so far!

treadingwater - 112 days ago
Next week weds is my scan! I can't wait to see my little one and also find out if it's a girl or boy. Finally! The weeks are sweeping by fast. We are almost halfway done. I've been feeling my lil peanut jump and flutter all around my uterus lol. It's a good feeling.

1morefor4 - 114 days ago
kekea--my gut says girl but i'd be happy either way although dd is begging for a sister so i'm hoping for a girl for her.

PaulaSoon2B8 - 114 days ago
Austin...most of babies have had a placenta blocking their kicks I get where you are coming from, but believe me in will feel it!! wish I would have read your posts prior, I would have suggested that to you to put your mind at ease...with my one baby my placenta was extremely large( so much so they made jokes in the delivery room) and with him I didn't feel much of anything the entire pregnancy...but every scan showed him moving all over the place!!

kekea - 115 days ago
1morefor4 I am excited for you. Do you have a feeling what baby is? I know that the reveal party is going to be awwsome.

1morefor4 - 116 days ago
hey ladies. i'm in countdown to my anatomy scan. only 1 week left. I am so excited, anxious, and nervous. I have a gender reveal party planned for the beginning of June so I'll have to keep things a secret until then (hopefully dh and I can avoid spilling the beans to anyone). it's really hit me that i'm almost to the halfway mark. and of course i'm super excited that i'm feeling little movements everyday now since early last week. I just can't wait for dh and my kids to be able to feel it too.

kekea - 119 days ago
Lol... and I can't wait to feel outside movement

mamalira - 120 days ago
I can't wait to find out what we are having!! So jealous right now. Lol

kekea - 120 days ago
Mamalira I am feeling a lot of movement now. I had another scan today and tech was right at 14 weeks she is a confirmed girl!

mamalira - 121 days ago
It is incredibly quiet in here! How are you all feeling? My husband got to feel baby move early last week. That is the earliest he has been able to feel any of the babies. Anyone else feeling bumps on the outside yet?

austinjeanxo - 129 days ago
Well had my ultrasound they changed my due date to sept 22nd placenta is in the front so that's why I'm not feeling any kicks. Still team green.

beckym - 133 days ago
Hey austin, we are here for you, I know, our ranks are few, but there are some of us still on here, which is a good thing! Did they say anything about the placenta possibly be I got in the front it's time? That would make feeling kicks very difficult.

austinjeanxo - 134 days ago
It is a bummer how inactive it is... I don't really have anyone else to talk to who understands my fears n stuff..... This is my only place.... Still not feeling any kicks yet =*[ worrys me. Ultrasound on the 21st.... Still gonna be team green

beckym - 135 days ago
I miss it being active too, this is a fantastic website available for pregnant women, I always rave about it to pregnant women I know or meet and give the website name, it has become a tradition for most of my pregnancies, I started using it when I was pregnant with my second in 2007-2008 and it was booming!

jamie86 - 136 days ago
I'll be moving to 19 weeks tomorrow and you're right, not a lot of people here. I miss it being active like it was years ago.

holz8519 - 137 days ago
Hello ladies and week 18.

beckym - 137 days ago
Dang I hope the picture thing fixes soon, I just moved to 19 weeks today, but I will peek at both, not a lot of people in here these days, we gals have to stick together. ;)

jamie86 - 138 days ago
Becky I'm glad all is well! The pictures won't work for me either.

beckym - 139 days ago
I can't seem to get any photos uploaded, it keeps telling me oops, and I noticed a ton of my old photos are missing from my page. 😯

beckym - 140 days ago
30 second scan went great, heartbeat is 146 bpm, baby is doing great, placenta is in a good spot, I am relieved that all us well. My folks went with because Johnny had to work. I called him and let him know all was well.

beckym - 140 days ago
We are going to get a quick fetal monitoring ultrasound today, not the full scan, but just to make sure baby is doing ok. Tomorrow is exactly one year since we lost our son Daniel, we are going to buy balloons to release and let him know we never will forget that we have an extra member of the family, and for the short time he was with us, he has impacted our lives for a lifetime, he will always be loved, and will be missed until we see each other again in heaven.

Ok, I'm freaking out a little bit, I just found out that sabra humus had a massive recall due to a listeria outbreak, be careful ladies! Listeria can lead to miscarriages in pregnant women. I am freaking out because I had but 4 of those, I wanted to eat healthier and try humus. Luckily the dates don't match those that were recalled but I am not convinced, a few weeks or a month ago I was feeling like I had a stomach bug or food poisoning, and I saw that pregnant women's symptoms are more mild with listeria, I have been feeling the baby move on a daily basis, but have been nervous that I haven't felt the baby move last night or today. I am thinking of saying yes to the u/s and give them 10 seconds, just so I can see the baby and know they are ok, I'm going to call my doctor and see if there are tests they could do.

beckym - 141 days ago
Cool, it would be nice not to have any more surprises in that area down the road, lol.

jamie86 - 141 days ago
Thank you! I think the company that does it is dna ancestory or something like that. It's neat. A friend of mine did it and found out he is part Irish

beckym - 142 days ago
Jamie that is awesome they can tell what background someone is by dna, I never knew! I can't remember if I congratulated you on the little boy so I will say it now, congrats!!

jamie86 - 142 days ago
Just checking in with you all. I'm 18 weeks today and baby boy is still doing great. Feeling more and more movement from him every day. I have my anatomy scan on the 21st. Becky I have no clue what all we of my background is. I know irish and possibly Indian but not sure which tribe. As for my father I have no idea. He's never been around. My husband is English and who knows what else lol. One day I would love to have the dna thing done that tells you all your heritage.

beckym - 144 days ago
I just learned a few days ago of another background I had but didn't know about, now adding Norwegian to my Danish, Irish, Cherokee, Spanish, German, Italian and French heritage. For my kids that is added to his Welsh, Irish, German, Italian, and Polish heritage.

beckym - 144 days ago
Yay! Week 18! Almost to the 20's. I am really enjoying this pregnancy stage, I am not uncomfortable, more energized than the first trimester where I wanted to sleep all the time, but couldn't. Feeling the baby move every day now at least 3 times. - 156 days ago
