ovarian cysts
"Pharmacy switched me to this from Ortho Cyclin. 
Seemed okay until the third week of use. Then, I started my cycle.... I skipped the final placebo week since I had already been bleeding for a week. 
Started a new pack of Estarylla thinking the bleeding would stop, but even after taking three more weeks, cycle STILL did not stop.
Switched back to my normal Ortho Cyclin pack, am currently starting on week three and STILL NOT STOPPING! Yes, I have gone almost 6 weeks without stopping bleeding. I was fine, and cycle was normal before switching to this nightmare of a birth control. 
Absolutely, 1000000% do NOT recommend if you are taking birth control to regulate cycles. This seems to have undone what I have worked almost a year to regulate."
