I have been on orthocyclen for about 4 years, I have shortened my period before my skipping the placebo pills but when I want my period to come I take the placebo pills and I get my regular period. (I do not stop my period often). I recently stopped my period for 3 months because of its inconvenient timing and this month I took the placebo pills, but I only got a tiny bit of spotting which started on day 5 of the placebo pill. What might be going on?
