QUESTION

Dear Midwife,
According to my last period, my EDD is Jan. 4th, 2010. That puts me at 28 weeks today. This is my 5th pregnancy, one of which was a miscarriage at 10 weeks. My last baby weighed 9lbs 12oz and my smallest was 8lbs 6oz, so we are expecting a larger baby. During the 21 week u/s he measured, yes another boy, 10 days larger which is no concern for me. However, at my last appointment I was 23 weeks and measured at 27. I know measurements can vary and aren't the most accurate but in all of my previous pregnancies, I had never measured large.

For the last month, I have been experiencing severe pelvic pain/pressure. It started out just sharp stabbing pains with certain movements and in the last week has turned into a constant pain. Rest doesn't help, they gave me a maternity belt and it's not helping. This past week I have also noticed Braxton hicks. Is it possible that I could be further along? I got pregnant while on the pill and wasn't sure if that could affect my due date.

I also have this feeling that something is not right. Not that something is wrong with me or the baby but that things just aren't right. My next appointment is in a couple days and I am very anxious about it. They are doing a repeat u/s to check his kidneys. I am already as big as I was when I gave birth with my last son. I know with each pregnancy you tend to show faster, but I still have 12 weeks to go and my last was a very big baby. Oddly, though, I haven't gained near as much weight thus far as with my previous pregnancies. Everything about this pregnancy has me feeling like a first timer.

Any advice/input would be greatly appreciated!

Thanks,
Cassi

ANSWER

You are just at the point where some women's sugars go wonky, and they end up with extra fluid. The ultrasound will say if that's what's happening. If you had an ultrasound in the first trimester, then the dating is pretty close, so I don't think that is the reason you are measuring big.

I really think it is not worth worrying about until you have that repeat u/s and know exactly what's going on. Just love your baby!
