I was put on Cerelle by my gp to help control heavy bleeding. (I had asked for an implant) I started on day one of my period, finished first strip, just started second. I have bled constantly. Fairly light except for the 2 periods I've had in 29 days (not including the one at the beginning). Should I persevere? Tbh, the idea of stopping now and having another period fills me with dread. Especially as it will be painful and heavy. I have endometriosis. I would appreciate advice thanks.
