I am a 28 year old female. I have a history of endometriosis, irregular/heavy periods. After I had my son my periods were still very heavy but became irregular. This month I had the flu and lost 7lbs. When I should have started my period I just started spotting and have been spotting now for 10 days. I have taken 2 HPT's and they were negative. I have had some bad cramping here and there. I am really clueless as to what is going on.
