You may just be finding out that you are pregnant. Congratulations! Many women are shocked to find out that they are carrying more than one baby! By four weeks, your developing babies will show up on ultrasound as two little gestational sacs. Although you cant see it on ultrasound until around week 6, the amniotic fluid and embryo are inside the entire time. Your babies are developing quite rapidly. During this time, the baby's brain, bladder, liver, kidneys, spine, extremities, reproductive tracts and heart are all beginning to develop. The first time your twins are visible on ultrasound, they will be about 2-3 mm long-which is less than a grain of rice. However, by week 7 and 8, each baby is about the length of two grains of rice . Cardiac activity can also be seen by ultrasound.

You might be noticing a great change in your appetite. This is one of the first signs of a pregnancy. Most women will experience an increase in their appetite between weeks 4 and 6. It is perfectly normal and may continue for the rest of the pregnancy. Because you are carrying twins, you should listen to what your body is telling you and eat accordingly. A woman expecting twins has about one and a half times the caloric need of those that carry single pregnancies.

It is also very normal to feel tired, or just plain exhausted at this point. Your body is working overtime to produce two healthy babies. You should try to get extra rest at night and rest as much as possible throughout the day. Eating a healthy diet and participating in light exercise will help.

An increased frequency of urination is a common complaint early (and throughout) pregnancy for most women. The uterus is beginning to grow and put pressure on the bladder, therefore making it hold less urine than normal and sending you to the restroom more frequently. If you experience burning or pain during urination, contact your caregiver.

Morning sickness and nausea may be worse with a multiple pregnancy. Although it rarely becomes serious, it can be frustrating. Nausea and vomitting can happen at any time of the day. Eating frequent, small meals should help ease your stomach. Many women also experience a hightened sense of smell and may experience an aversion to certain smells and tastes.

A twin pregnancy seems to cause more heartburn, and does so earlier in the pregnancy. This is because your uterus is larger. Antacids will help with heartburn symptoms for most women. Rather than lying down after a meal, take a short walk or sit straight up for a while to aide in the digestion of your food. You may also notice that you feel constipated. Drink lots of water and increase your fiber intake.

Many women experience nosebleeds and stuffiness during pregnancy. This is because the mucus memranes in your body have an increased blood supply. The increase in blood can make the mucus membranes in the nose become swollen and secrete additional mucus. Many pregnant women also experience a sensation of breathlessness. The feeling will get worse as the pregnancy progresses. It is normal to have an increased heart rate. This is from an increase in blood supply and decrease in blood pressure.

Breast tenderness is a common symptom of early pregnancy. Breast tenderness and swelling seem to increase in women who are expecting twins. You may also notice a darkening of the areola-the circle around the nipple on the breast. Support your breasts properly during pregnancy.

To think about this month:

Finding an obstetrician
Finalize all insurance concerns or questions
Apply for Medicaid if needed

At the doctor

During your first visit with the doctor, he or she will be going over information regarding your pregnancy. Address any questions or concerns that you have. They will also be doing a complete work up on you, including:
1.)Blood pressure and vital signs
2.)Physical exam-heart, lungs, breasts, abdomen, and pelvic
3.)Family history questionaire
4.)Urine Sample
5.)Blood samples

Just found out that I have twins today via IUI. So excited since we are still trying for our first(s).

Congrats on all the twin pregnancies. I was curious if anyone conceived their twins with IUI? I'm currently doing IUI w/injectables and have 3 follies on each side but the biggest ones are on my left side which is blocked. Anyway, I would love to have twins!!!

I have a question.. it says that tender bb's often increase in women expecting twins. i'm curious, because my tender bb's are the first thing that i noticed, when i thought i was pregnant before i found out for sure. i've had them for the past 8-9 weeks now, but this is my first month that i completely missed my period? ive never had any symptoms to arise before i started my AF. and it wouldn't make sense them to be so sensitive the whole time even now!? and i took a test nearly every other day because i could have sworn i was pregnant, but it didn't come back positive, til i was 8 weeks (approx, haven't had an appt yet, thats just going off symptoms from drs) has anyone else experienced this?

Hi ladies! I'm 5wks 3days pregnant, I had a miscarriage last cycle and then obviously ovulated immediately afterwards, as I began feeling those familiar bouts of nausea again just two weeks ago :-) As my Doctor decided to monitor me closely after the m/c and an extremely high hcg level I was sent for an ultrasound yesterday! And yep....theres two visible little gestational sacs one on either side!!! I'm so shocked....but elated what a rollercoaster :-)

What a great website! I just found out I’m 5 weeks and 2 days with twins. Very exciting news but very scary, I’ve had 2 prior miscarriages and no babies yet. My doctor is setting me up with a specialist but haven’t heard anything as of yet. The waiting game is tough. Just crossing my fingers that everything goes well.

We had our 4th ICSI and following two embryos (3 days old)transfer on 27 September and finally had a positive result on 9 October (the happiest day of my life). We had our first ultrasound scan yesterday afternoon 28 October. We saw two sacs one with heartbeat rate of 124 bpm measuring 7.1mm and the other had slow and irregular heartbeat and measuring 5.8mm. We were told that the small embryo with slow and irregular heartbeat may not survive. We have another appointment for ultrasound on 18 November to see the growth of these embryos again. Feel very torn and very confused at the moment and worried as not sure what will happen, whether it will affect the other one. Any ideas please. Many thanks. Thank you.

AAwww!! Hello, every one! Hmm.. I found out I was having twins at 5 weeks gestation. My husband and I joked around that I was having twins because I was literally eating every other hour, and because I was sleeping so much. We didn't really think I was having twins, so when we found we were pregnant, we were shocked. His grandmother had 3 sets of twins. I didn't think I would have twins, but I did... :)

What was anyone's first sign that tipped them off that they may have twins?

jessiboo17 - Sunday, 18 Oct
Just a quick question... I am 9 weeks and measuring 13 weeks. Just curious if this could be twins. I'll find out in 3 weeks at my ultrasound, but my other two singleton babies never felt like this and I swear I can feel movement in there that feels like bubbles, but I know it's far fetched. I'm just curious if anyone out there with twins are measuring bigger like me and can feel movement. I don't know for sure, but I really am speculating that it could be twins.
