So normally I have heavy, long (10-14 day), and irregular cycles. But this most recent one has been VERY heavy and full of clots. Is this normal? My last cycle ended on the 21st of Aug and I started again on the 3rd of this month. I've been having to change a super tampon and my over night pad every hour to hour and a half. The clots have been about 1-2.5 in long and about .5 in thick. I'm cramping horribly but have no back pain. I'm thinking it could be due to my endometriosis but I don't want to just write it off as that if it could be something else.

Make an appt. with your gyno. He/ she can test your hormone levels. 10-12 days of bleeding is too long. Let your Dr. help you regulate your cycle.
