Bea,I had that with all of my kids except Seth.With him, I had low fluid and it was so low that they wanted to take him early.
I was told that the reason I had to much fluid was because the babies were peeing more and that was actually a good thing.Where as with Seth, he wasn't peeing much at all.
My kids all measured to big when they did the tape measure on my belly.She may have a big baby is all.
Amber was 21 in. and 8 pounds 2 ounces
Devin was 21 1/2 in. and 9 pounds and 4 ounces
Jordan was 21 1/2 in. and 9 pounds 9 ounces
and then Seth they took early because of the low fluid only was
21 in. and 8 pounds even.
I am sending MANY prayers that way that it is just because the baby is gonna be big--or is peeing alot.
My prayers are with you all right now Bea! Think of it this way, if they were seriously concerned something was wrong, they'd be rushing her to the specialist, but they aren't so I'm praying it's just precautionary!
