Estrostep Fe and cramp

I had been taking Estrostep for about 2.5 years, and it was almost like i wasn't on any pills. I had normal symptoms, I'd bloat a lil the week before my period, and get hungry. The day my period would start i would get extremely tired. But otherwise i had no complaints it was the first pill i was ever on. It was so predictable i had calculated my period down to the hour of the day it would start. But around the end of the time i was taking it i started to cramp a little more than usual and also bleed a lil heavier, and longer. So i figured it was my body getting used to the pill, so my Dr. decided to switch me, and so far i've been thru 2 other pills, and i def. don't recommend Orth-Tri Cyclen Lo, i was a maniac.

so far so good, but I think the ferrous fumarate is making me cramp up...but I'm starting my period, too, so I don't know. I've been popping IB Profen and Tylenol all day and nothing seems to help. Anyone else have this happen?
