Recently me and my boyfriend had sex the day after my period ended. We had sex once and everything seemed normal however, during our second time that day my boyfriend noticed I was bleeding heavily. We stopped and i went to get my pants and underware and then figured out that they too were covered in blood. I had double checked before we had sex that I wasn't still on my period and the condom came out the first time with no blood on it. I have been bleeding for two days (the first day like the 2nd day of a period and then today like the last day). My question is could this be my period still and maybe I just thought it was over or could this be something more serious? I didn't and am not currently experiencing any pain. Has this ever happened to anyone?
