Last night my boyfriend and I were having sex and then out of nowhere I started crying then a couple of seconds later I started laughing because I was crying during sex. My boyfriend had a horrified look on his face and didn't understand what was going on. He asked me what was wrong and I told him that I didn't know why I was crying. I'm 11 weeks pregnant so I'm wondering if that had anything to do with my hormones? I've never done that before. This is my first pregnancy also so is that normal?
