Some women don't at all.. I didn't at all with my previous pregnancy til the last trimester, this pregnancy it was one of my first symptoms, so it varies. Usually the last trimester or end of the 2nd is when your uterus really starts weighing on your bladder.
I wish I didnt lol. I go sometimes five times in the middle of the night
I have to go all the time i'm 26 weeks. Matter of fact i gotta go right now
