I've been to my doctor every week because of this, since I found out I am pregnant and they say there is nothing they can do, "nature will run it's course" some women have " periods" every month as if they are not pregnant but I'll stop bleeding for a week and start right back up... they call it a Threatened Abortion or miscarriage, I questioned when they called it a Threatened Abortion they say it's the same thing and is actually they medical term for miscarriage. I'm unsure. I didn't start bleeding until after my first appointment. I'm very scared and worried but am on a scout camp out with my oldest and don't have my car...
