I just started my 25th week. And about an hour ago start having some period like cramping. I just took a dose of Cal/Mag , and am drinking more water. But I just kinda feel off. Also my uterus feels extremely heavy (common in pregnancy I know but its more noticable right now) and I feel some pressure. Baby did drop a couple days ago!! I am not sure what to think!! Contractions I am used to (as this is pregnancy #4) but menstraul like cramps aren't common for me. As of right now no blood, or extra discharge, although I keep feeling like I am gonna start my period!! Its very odd feeling!
