Does Ortho Novum Has Any Side Effects With Cramping And No Periods?

I was on depo for 6-7 years for bc reasons, I just turned 45 in oct. and my family dr. said I couldn t have the inj. anymore and put me on ortho novum 7-7-7, she said wait 1 mo. b4 starting it. I waited the months of oct & nov. waiting for a period, notta. so, sunday, dec. 1st I decided to start the pill so I could have a period and have had contracting cramps for 2 months but no bleeding. I started the 2nd month of pill 5 days ago and m feeling terrible. what do you think is going on in my body as a 45 yr old identical twin? (I know this has some sort of early onset of menopause according to goggle)
