Lol,

i was in the exact same boat as you. In good shape flat stomach and before I even knew I was pregnant my soccer shorts didnt fit an that is when I knew something was a miss that and a missed period. Needless to say I was also getting married 12 weeks in and my dress had to be taken out 2 sizes. Most if it is caused from bloating. When you had your ultrasound did they say you had alot of amniotic fluid. That's what happen to me.

Hope things go good

Everyone carries differently. So dont worry keep up your fitness routine which is safe when your pregnant,as long as you are only doing the same things thst you did pre pregnancy. It will go away quick :d good luck

Omg I am the same way and wahs weirder is my tummy is getting all big but liek I am not gainign weight. I played sports all my life and have been in great shape. I had a doc appt the other day and the doctor comes in and goes wowwww you are a bigg 4 months haha she wanted to test me for twins too... I guess it happens

i am 7 weeks and my belly is huge this is my second preg. and last week i was wearing my jeans and my belly has formed so big and i am not eating like i did my first pregnancy been so sick.is this normal? why is my belly so big?

i'm going through the same thing. second pregnancy and started getting big around 5 or 6 weeks. I'm 12 weeks now and look 5 months along. The doctor said it's normal for a second pregnancy because everything's has been stretched out before. I hate it though, becasue no one else understands...my co-workers look at me funny becasue they know how far along I really am. very frustrating...I wish there was some way to de-flate!

I am 11 weeks pregnant and this is my first,My belly is getting big and my old pants doesnt fit me anymore its all tight..is this normal?i was wondering how do they calculate months of pregnancy as well...
