I stopped Microgynon in July last year and I am still waiting for a period 8 months on... I think I am starting to go insane
If you don't get it soon, you should go to your doctor and see if she will prescribe you progesterone to kick start your period. It is not healthy to go too long without a cycle.
For me, I came off of the pill last April and it took me 8 months to regulate into a 32 day cycle. I was on Yaz for only a year and was on Loestren on and off for 8 years. I find that temping is a lifesaver with crazy periods. I can at least know if I ovulated and when my period is coming.
