I've been having all of these symptoms like I'm pregnant.. my last period was during the last week of feb and I had sex on march 13- 15. But yesterday night I started bleeding this brownish, dark red blood. I usually get cramps during my period, but I have none right now. I'm still bleeding today (it's not a whole lot of blood but id say that it is a little more than just spotting) what do you think it could mean? Am I pregnant, miscarrying, or is this my period?? Took a pregnancy test but it came back neg, I think I am prego tho. Need advice!
