For the last two months I have had clotting and chunks of blood come out when I am on my period last month I was on for 3 weeks but one week was spotting and then there was a week and a half of clumping and bleeding then regular bleeding and it is the same so far for this week. In November of 04 I had laparoscopy done and I had pulps and the doctor remove then he told me that the chances of me getting me was less than 2% with invetro so after 6 months I could stop taking the pill. I stopped in march of this year and didn't have a period until may. Any ideas on what the clumping or chunks of blood are from

I am uncertain what these clumps may be. Is there a chance that you may have more polyps?

When you bleed this heavily it is extremely important to get to the doctor asap due to loss of blood or possible menstruation related anemia.

Please contact your doctor as soon as you can.

You need to contact your doctor to make sure this is nothing of importance.
