HELP!

My period is the worst time of the month for me. It is 3 days long with the first day being the worst. I have severe cramps even with Advil. Without Advil I throw up, have hot flashes, and black out. On the first day I pass 2 pieces of flesh. It is NOT a blood clot. When they pass it hurts to the point where I am doubled over. I normally have to stay in bed until I pass those fleshy pieces. Once they pass, I am fine. My period is no longer heavy and I do not have cramps. Day 2 and 3 my period is so light to the point where I free bleed without the concern of leaking. This happens every month and has for years. Has anyone else had a similar experience or know anything about this?

Thanks!
