Has anyone ever been pregnant but bleed like a period? I read online that it could be possible to bleed like a period while pregnant it's called decidual bleeding. I want to know am I experiencing decidual bleeding or am I on my period. I've had this happen to me before I got my period each time & the exact same time I was supposed to get my period but I felt pregnant. I went to the doctor they said I was indeed pregnant but miscarrying. Now I'm scared, I feel like I'm on my period which is why I posted I got my period I'm not pregnant!!! But now that I think about it I could be pregnant & experiencing the same thing I went through before.
