Hello! I am 7 weeks pregnant. A couple of days ago, I started bleeding, and the next day there were brown discharge. It's been three days now, but it's less. Today I saw my doctor, who said that I have placenta previa so I started bleeding. She prescribed progesterone cream and injections, as well as Dufaston. She said at 13 weeks there will be an examination, if she doesn’t like the cervix, it will be stitched. Before this pregnancy, I had one empty (at 6 weeks I did vacuum cleaning). Three months later, I got pregnant again and this pregnancy lasted for 5 months and all four months I bled, I also used progesterone cream and injections
