I have been having sex with my boyfriend unprotected, I spotted a few days after the last time we had sex and then I started my period, my periods are never late or early, I stated 1 week early this time, my periods are always 5 days an heavy for 2 days an pretty light the last 3. I've been bleeding for 7 days now really heavy non stop, and I have had some clotting like ranging from die size to golf ball size. I am concerned something is wrong, what could it be, this is not normal for me at all.
