Yes! But that didn't happen to me until at least 12 weeks when my uterus was growing and stretching. It's very painful to my muscles under my belly button! Almost like it's pulling on them.
Maybe sooner because it's my second??
Oh yea. Luckily I don't sneeze much but the last few weeks I have been. And yes, if your bladders full you will definitely pee (makes me feel old, I'm only 25 lol) just cross your legs and hold your tummy :)
Lol I'm 28 haven't peed yet!!
