Hello ladies. I know we're not supposed to start threads for every little thing but I'm a FTM and really scared. Last night I had a little bit of bleeding and some intense pressure in my uterus. It wasn't heavy, in fact I only noticed it when I had a BM, it was pink. It never even made it down to my underwear. It has since stopped and my pregnancy test was darker today than any other test I've taken. My MIL is a nurse and she thinks it was just the placenta implanting into my uterus since I'm only 4 weeks today. I'm still scared because AF is supposed to start today and the only symptom I'm experiencing is cramping and backache. Has anyone ever had something like this and been fine?
Again I know it says not to post about bleeding or use this board as a dear diary but again I'm a FTM and really scared. Thanks ladies.
