Sunday, my fianance and I had sex well i starte dspotting shortly after only enough for liners. Okay well my period was scheduled for the end of this week. So i figured it brought it on. Well yesterday i bled lighter than normal period light pad dark brown/almost purplish colored blood. Well today i had minor period cramps bled a the same little amount this morning and now nothing! Idk if it was my period lighter than normal lasting a day or what. (My periods are normally heavy and abt 5 days long) has this ever happened to anyone? Whats going on?
