I started my period on time, it was a little bit more brown then red. That night i had really bad cramps, mainly on my left side. I was basicly spotting(not a heavy period) for 4 days. I stopped then 2 days later I started spotting again but this time it was brown, no red. By the way I had a pap smear 2 weeks ago and it came back normal. Can somebody give me some insight on my situation, please...
