So normally my boyfriend and I use condoms, this time we stupidly decided not to. Last night we started to have unprotected sex and then decided to finish with a condom on. Then we decided to do it in the morning and I think he finished inside me and doesn't want to scare me and tell me he did. A few hours passed by and I started spotting, now it has been even more time and I have a full blown period with cramps and everything. Mind you my period doesn't start for another week or so. What is going on?? Can someone please help.
