So I started my period march 22 an ended on the 26.( Ok my periods are always really bad like almost 18 tampons a day I go throught an last 7 days.) This time it was really light an 5 days I used like 10 tampons BC most the time I didn't need anything. Then 3 days later of ending my peroid I started again but when I would pee for 5 days. No cramps not heavy nothing like my peroid has been for the past 9 years. What could be goin on? I'm trying to get pregnant but it's really hard I miscarry a lot. What do I do? I went to the dr an they don't do anything this is getting really hard. I need to know what's goin on BC I want to have another baby. Please help me out.

My period finished on the Wednesday. The following weekend I started getting brown-black bleeding. I didn't consider it anything to worry about but as of the Tuesday I had heavy black clots streaming out of me from when I woke up. This followed by a period all over again. I usually have regular periods and am not on any kind of pill and have had no implants. This was also with pain in my lower abdomen area on both sides. I am also not active and haven't been for many months. Any ideas as to what this could be?
