I read on google that a lady did the same exact thing and she thought she wasn't pregnant because of her period, and the next period was late and she found out she was pregnant. It's been 3 weeks since having sex and all that happening, and I am eating a crap ton (maybe because I'm nervous) I have a little bit of blood in my discharge (implantation bleeding?). Have any of y'all had a similar experience? Is it FULLY impossible to have a period while pregnant? And no, I didn't mistake my period for anything... it was right on time and I had all my normal stuff with it. Any advice?
