I started bleeding today at 11 weeks I rushed to the hospital right away and was thinking the worse thank god I was checked out and my baby was measuring accurate a day early actually and heart beat was normal. They said I have a small subchorionic implantation bleed and should rest and avoid sex. I called my doctor and I will be going in this week. Has anyone else had this happen. bleeding as now stop has one spot since I got home from the hospital. Happy my baby is okay.
