menstrual disorders
"By BMI I am overweight but not obese, and was tried on the patch and several different birth control pills without success. Bled more often than once per month and/or longer than 5 days/month. I was given samples of Loestrin FE 24 which worked flawlessly for 3 months, so prescription was written for Microgestin 1/20 (generic form).  After 1 week of Microgestin, I was 3 *hours* late with 1 pill (1st time I have missed ever).  By the time I took the late pill, breakthrough bleeding had already begun.  A week later still bleeding and it has become stronger - still not as strong as a regular period had been.  Going back to Loestrin FE 24, hope it works again."
