Okay so after reading so many things about implantation bleeding and how tired people are of hearing about it. I have a question. I had unprotected sex on June 14, 2015. I recently just got my period on June 23, 2015. It was a day early but on time. I thought it was implantation bleeding but it has been three days and it's bright red blood. Not to mention I'm on it tho tricyclen lo, I rarely miss a pill and take it on time or around the same time every night. So it can't be. Since I had sex about eleven days ago would it be possible that since I am now fertile that I could possibly ovulate. Or is the sperm dead by now? I have no idea what to think. Reading about all of these possibilities is scary. Could I end up pregnant? Please help
