Very akward question here....

I know that you aren't suppose to wear tight pants while pregnant but I don't think that just sucking in won't do much. Like Milliesmom said, I won't do it too much though.

Hmm, being 5 and a half months pregnant, baby is getting kinda big in there, I would say ask your physician, because to me it would seem as though it would hurt the baby. Even if its not cutting off oxygen or whatever, I would imagine if your are sucking in so hard that you cant tell your pregnant, your uterus is a muscle, so it would contract in such a way that would squeeze the baby. And it may stress the baby out enough that it could throw you into pre-term labor, I wouldnt do it myself...but just to be safe, ask your OB/Midwife. At a month pregnant is different lol, but yeah I would really check before doing it again.

I am only 3months 3wks along (15wks) and people can tell I am pregnant and I can actually feel the baby moving and kicking and doesnt feel like gas bubbles or anything. Even though this is my second time around, but is that normal ?? I know each pregnancy is different.
