My period was between Sept 01, 2010 - Sept 07, 2010, and I'm having spotting now, after it. When I pee, sometimes it's not there, but other times, it is. It's just a little, but it's something. It doesn't hurt at all. I'm wondering if it's because I had intercourse for the first time last month? Could it be messing with my period? This has never happened before, and it's bothering me. Is there anything it could be?
