I'm 27 weeks and just today have been experiencing enormous amount of pressure in my rectum. Also feel like I need to pee (or even poop) but can't. I can't sleep and I'm miserable and feel awful that this is as bad as I've felt this entire pregnancy. Also feel slight crampy. I've had nothing to complain about until this, and it's so uncomfortable! Has or is anyone else experiencing this? Is it normal or is it bad? I don't think I have hemorrhoids because I don't feel any bumps or lumps around there, but I do feel uncomfortable sitting because of the pressure in my rectum. Help me please! What can I do?
