I had surgery in August last year and again in December (ligament repair on my ankles). Since December, my periods have been insane. There might be a week out of a month I didn't bleed. I went to see a doctor. She put me on Sprintec birth control, but then things got worse and the bleeding wouldn't stop. Then she had me take Dasetta. 4 pills a day for 4 days, then start a pack like normal. The bleeding stopped, but less than a week passed before I started bleeding again. I've been tired all the time and having some back problems as well. These things are not normal to my period. What could be going on with me if birth control can't stop the bleeding?
