Hello ladies! I'm pregnant with my second child. My blood is 10 weeks old (I think). Since week 8, they put me in the hospital and I stayed there for 7 days. I was taking vaginal progesterone twice a day. Now it's bleeding again at home. I take dicontin and Dufastans. I'm taking vaginal progesterone again. It's bleeding again. Is this not scary? Has anyone had this happen?
