Is it possible that my doctor is wrong about how far along I am?

Question

I'm stationed in Germany and have to go out to the economy to a German doctor. So the whole language barrier sucks sometimes even though my doctor does speak English.

but anywho ~ As of today(wednesday) I'm 34 weeks. But heres the problem. For the past 2 days now I have been getting these period cramps that feel like I'm about to start my period and they just keep on getting worse. When they do stop, i'll be fine for a while but than my lower back will start to hurt and than the cramps start up again. (getting really annoying)

Well let me explain a few things before i ask my question: when i was 31 weeks i went and saw my doctor and he told me that i'm having a big baby. she weighed 4lbs and 6 oz and was 44cm (17.3 inches) well here i've been thinking that shes just going to be a big baby because i've read some books and at 31 weeks the baby is suppose to be around 3lbs and 16inchs. And my doctor told me that I was 31 weeks but that baby was growing like a 34 week baby.

SOOOOO now that i'm getting these cramps and feeling a whole lot of pressure down south, i was wondering if it's possible to have your period while being pregnant? I ask this because my doctor is going by my last period. Well, I had 2 periods in december. One on the 5th and than one on the 26th. So my doctor went by the 26th. BUT if he would of went by the 5th, than i would be 37 weeks now (not 34) and the size of my baby would match up with a 37week baby. SO, is it possible to have a period while pregnant? and that the doctor could be wrong?

And anyone have any advice on how I should bring this up to him? my next doc. appointment is the 30th but I'm thinking I should call him and see if i can come in earlier just because of all the back pain and cramps. : /

Answer 1

Have you had an ultrasound scan, with pictures? Not one of those where they just listen to the heartbeat?

Those are rarely wrong by more than a few days.

But I don't think she sounds that big, Babies on average put on half a pound per week in the last few weeks. So at 40 weeks yours will be a bit under 9 pounds. That's big, but not implausibly so.

Answer 2

have they done any ultrasounds...because technically the baby can be 4 pounds at 31 week. mine was 3 pounds 1 ounce, but I have heard of bigger...post us on that part..the ultrasounds are a little more reliable than a guesstimate.

Answer 3

Seems related to ur answer

Answer 4

ok. First. Yes, you can have your period when you are pregnant, but it sounds like you are having contractions. If you have more than 4 in one hour, call your doctor.  Second, did the doc determine your due date by your LMP or an ultrasound? Normally, they use an early ultrasound to determine the gestational age of your baby. This is more accurate than the size of your baby later in pregnancy because a sperm and an egg are all relatively the same size, but as babies get older, they vary in height and weight. If the doctor did an early ultrasound to determine your due date, go by that. It is more accurate than the size your baby is now. Also, they might say the baby is that big, but it is not an exact science. I have friends and family members who were warned that their babies were larger than average, but ended up being perfect sized when they came out.  

I would call and see if you can get an earlier appt, because like I said, it sounds like you are having contractions. and again, more than 4 in one hour means you should call the doc right away, you may be in labor!

Good luck!
