I recently went back on orthotricyclen after being off it for a few months. This is my third month back on it. One week before my period was to start, I started bleeding lightly. This lasted the whole week before my period. Now I am on my period and it is much, much heavier than usual, with a lot of clotting. I also have more severe cramps than i've ever had before. I've been reading a lot about uterine fibroids, endometriosis, etc. Does anyone have any thoughts on what I may be dealing with? I do plan on seeing my doctor, but have not made an appointment yet.
