My boyfriend and I were messing around and I kinda slide his penis inside but it only made it to the entrance of my vagina. Moments passed and got on a condom and had sex. Three days later I started to bleed and it felt like my period symptoms but it was bright red heavy and it wasn’t suuuper light either. I’m on the second day now and it’s gotten lighter. I googled and it said it could be implantation bleeding, could this be true? The blood even has clots in it which I’ve read that implantations shouldn’t have. I’m scared but in despair for guideness.
