I have been on birth control for 5 years off and on. I started my pills again about a month and a half ago. My pills always regulate my period. I can usually skip a period if I want. I had what I thought was my period last week and have been spotting irregularly for 2 weeks now. sometimes it's dark borwn and other times it's bright red. sometimes it's mild and other times it's heavy. Associated I have had very discomforting cramps. I have had unprotected sex but he pulled out. Which I know is not safe. I just don't know what to think or do? HELP!!!!
