I recently had a miscarriage in august well since I stopped bleeding we've been having unprotected sex (since 8/16/14.) well I was suppose to get my period this week but I only had like a little Brown spotting on throughout the week & some pink spotting but on Friday I had some what some heavy bleeding but not enough to change a pad now between Saturday & today no bleeding or spotting at all ? Could this be implantation bleeding I've never had it so I don't know.
