I started spotting 5 days prior to my period. My boyfriend and I have unprotected sex and unfortunately we had sex the time I was ovulating. The spotting is a pink with a hit of brown and red and I don't know what to do or who to ask. I have mild cramping and some lower back pain. I've started my period around the 20th of every month and this month is really early. I don't know what to do or what to think.. what should I do? Please help?
