Born & Birth stories





By the end of this week, you will most likely be expecting your period to come. However, if you are pregnant your period will most likely not come. Some women do experience some spotting or even a light period. It is also possible to have your period and still be pregnant! If you do miss your period, you might begin to think about a possible pregnancy! Home pregnancy tests are not as reliable as blood tests at this point. A blood test will detect a positive pregnancy test at this point because the hormone, human Chorionic Gonadotropin (hCG), has been secreted.

At this point in your pregnancy, your growing baby is very small and is about 1 mm in length. One mm is about half of the size of a typed letter `o`. You are still not showing at all and you have not yet gained any weight. Even though you are in the very early stages of your pregnancy, many great changes are occurring. The implanted embryo is embedded deeper in the lining of your uterus and the amniotic cavity is beginning to form. The placenta is also forming and will be delivering oxygen and nutrients to your developing baby. This week the blastocyst begins to transform into an embryo. The embryo will have three different layers with different types of tissue. The inner layer will form the lungs, liver, digestive system and pancreas. The middle layer will become the skeleton, muscles, kidneys, blood vessels and heart. The outer layer will become the skin, hair, lenses of eyes, tooth enamel and the nervous system.


A clear result. If you tried it a few days ago and the result wasn't as convincing as in this picture, try it again now to be sure!

Even though you have not yet gained any weight, you need to be prepared to gain weight during pregnancy. Gaining a healthy amount of weight is crucial for the health of both mother and baby during pregnancy. You can control your weight gain by eating healthy and nutritious meals and snacks. During pregnancy you are eating for two, but that does not mean you have to eat twice as much!

Your body now starts producing a hormone which stops you having your period, and it shows in your urine.

It is now possible for your pregnancy to show up on blood tests, and even home pregnancy tests.

About 1 in 3 women have a light bleeding at this point. This happens before you would expect your period to arrive. Unless accompanied by cramping, backache or increased bleeding, a small amount of blood being discharged should be considered as implantation bleeding which is nothing to be concerned about.

At this point, your baby is still not visible to the naked eye.

jamie86 - 19 days ago
Delarla- if all works out this will be our 4th living. In the last year I've lost two babies around 15 weeks. The first one we didn't know until I was 19 weeks. Praying that with extra meds this time everything will be just fine though.

jamie86 - 19 days ago
So sorry ana!

delarla - 20 days ago
anabeana42 I'm so sorry to hear that. How far along were you?

anabeana42 - 21 days ago
Early miscarriage. Back to TTC! Good luck for healthy pregnancies and babies everyone!

delarla - 23 days ago
Congrats everyone! This will be my fourth baby with this site. I have 2 girls and 1 boy. So far some minor twinge iny lower ab area and my breath are starting to get sore. It's so hard not to tell everyone we're expecting again... then again I know most wont understand why we decided to have 1 more but to each their own.

Ryskay - 27 days ago

Ryskay - 28 days ago
the last few days have been to harsh for me been hit with morning sickiness hard :( spent most of my day on Christmas day in bed...I hope everyone is doing better then me lol!

lillianshappymommy - 33 days ago
That Makes sense about the hcg levels. My doctor kidded about twins and then I freaked a little lmao although I knew it was just a joke. Lol anyone else feeling bloated? Last night had my first bout of puking. Ugh I completely forgot how intense puking is when pregnant. 😕 ugh. Any who I won't be on tomorrow cause of Christmas, but wanted to wish you all a merry Christmas!!

Ryskay - 33 days ago
I was the same ways with my youngest son when I was pregnant with him all I had to eat was nothing but pizza, with my daughter I couldn't eat anything or drink anything my m/s was so bad I was in the hositpal I think 5 or 6 times because of it. with this pregnacy thou it seems to be ok I'm crossing my fingers that the m/s isn't going to be bad like it was with my daughter. So far katchup is the only thing that doesn't like me very much at the moment which sucks to because I love it with my fries :(

kirty - 34 days ago
Thank you :) The darker line could be your hcg levels are higher. I took my test last week with a faint line and one on sunday which was darker they get darker the further along. My last pregnancy i took the test a week late and the positive line was darker then the control line.

lillianshappymommy - 34 days ago
Congratulations kirty! @rysky I don't think I would survive at the moment without ketchup! Lol all I can seem to stomach Right now are burgers (not even kidding with my first it was pizza. Ugh) Had my pregnancy intake appointment today! Next week I am scheduled for the full blood work etc. I can't believe this is happening you guys I am so freaking excited.lol Can I ask you guys a weird question if the line shows up dark on your pregnancy stick what does that really mean?

Ryskay - 34 days ago
@lillianshappymommy, I know the feeling I'm the same way at the moment the worst thing for me thou is katchup :(

kirty - 35 days ago
Hi Ladies, i am officially pregnant i got my blood test results today to confirm. I took a few pregnancy test last week and got a really faint positive so i went to doctors straight away. This is baby#5 for me i have 2 girls and 2 boys. :)

lillianshappymommy - 35 days ago
Thank you @Ryskay. So psyched for baby#2. Oh my god. I absolutely hate feeling nauseous. I would rather just throw up then feel sick all the time.:( It was one of my first symptoms and I HATE it. ughh. I smell things strongly. Like for instance we have a real tree in the house and we decorated it with plastic ornaments and stuff and I can SMELL the PLASTIC. and The tree is just soooo overpowering. ughh

Ryskay - 36 days ago
starting to feel abit of nausea now, and that I find that I'm having trouble going around some foods :(

Ryskay - 37 days ago
@lillianshappymommy congrats on your bfp :)

lillianshappymommy - 37 days ago
Hey ladies!! I am so excited to be back on this site! I am officially pregnant again! I took the pregnancy test on the 18th and right away it showed up positive. I wasn't surprised though seeing as how I knew I was pregnant. I was just double checking lol. I have a 3 year old (she will be 4 in April) and I have had one mc before this one, but I am not too worried. I will be going to the doctors for the initial check up etc after the holidays because lets be real I will have no time before then. lol. I am super excited to connect with new ladies this time around(this site kept me SANE during my first pregnancy.) I look forward to getting to know everyone!

littlemamadit - 38 days ago
Well, this will be baby NO. 10 for me. I was always convinced that I KNEW I was pregnant right away. I was able to confirm that this time around. I taste metal in my mouth soon after I conceive. I checked lots of charts. According to the charts, I knew I was pregnant before the egg implanted :/ I am going to tell the rest of my little ones on Christmas Day. Let the party begin!

Ryskay - 40 days ago
congrats happybabymama3 on your bfp :)

skydive - 40 days ago

eliciamadora - 40 days ago
Hi guys. If this isn't allowed please delete! I mean no harm! I couldn't find any pregnancy groups for August 2015 on facebook so I made one. It is a closed group so only members can read what is posted there. Only a few members so far and I'd love to bond with women due around the same time! Please add and message me on Facebook ( Elicia Binman) if you would like to join it, I would love some company in there! Or search on Facebook 'August 2015 babies' and request to join :)

Ryskay - 41 days ago

SummerGirl - 41 days ago
thanks mrsbugs, its really good to finally be in here fx that this is a sticky bean. I'm feeling very excited and can't wait for the weeks to pass congrats on your bfp as well :)

mamabearof3 - 42 days ago
So I know that I am in week 5 but thought I would post in here anyways since I just found out that I'm expecting..I'm feeling really good for most part the news for me is still sinking in lol..feeling tired and my sense of smells seems to have gotten stronger the past few days I'm feeling hungry alot more now and thats pretty much it at this moment.

mamabearof3 - 42 days ago
xEricaLynn I'm sorry to hear that, maybe give her sometime for the news to sink in she will come around I have gone throw the same with my family.

xEricaLynn - 42 days ago
I told my mother about me being pregnant, and she wasn't supportive at all. She knows I've been struggling with my brain disorders and the immense pain I'm in every day. I have to wean off my pain medications, which is causing me so much more pain. I also have anxiety and panic disorder. I wish my mother could have at least been a little supportive though. Sigh.

PregnantAnnie - 42 days ago
The fb group is closed so no one can see what u post unless they're in the group as well.

mrsbugs - 43 days ago
Congratulations summergirl! No I'm not joining the FB page I want to keep my pregnancy a secret from friends and family at thr moment. I've told my mum she's delighted!

SummerGirl - 43 days ago
