I'm 29 weeks today, and for the past couple days I have been feeling menstrual type cramps in my lower to mid abdomen. They come and go throughout the day and night but are not regular enough to time. My stomach doesn't harden, so I know it's not BH (which I already have enough of) They do not go away when I stand or walk around. They do however get worse when I lay down or after I eat anything. Has anyone experienced this?
