I had a baby 8 months ago, and after that I was having normal periods. My first one was very heavy but normal after that. Well in September I missed my period and the 2nd week of October I started spotting. For a month I had brown and red bleeding not to heavy though. I went to the Dr last week he gave me a pregnancy test which was negative. He told me the irregular bleeding was normal due to having a baby and he put me on because to regulate it. Well the day after I went I started bleeding heavy bright red and passing big clots so I just assumed it was my period, but that was a week ago and I'm still bleeding heavy. Any ideas of what it could be?
