progesterone birth control

JustJG
I was on a progesterone birth control pill for about 3 months after my iud fell out. I did not like the pill because I did not get my period at all while I was on it and I also had a bunch of acne pop up that I never had before. So, I stopped taking it. My doctor wasn't very happy with me but I wanted to cleanse my system for a few months before ttc. I have been off the pill now for 2 months and my acne has cleared up but I have not had a period yet. I have been reading a lot online about the effects that birth control can have on your body and that it can sometimes take up to a year to get your body back on track. My doctor said she wants to see me if I don't have a period in the next month (3 months after going off the pill). I have had pretty regular cycle when I wasn't on birth control before. Does anyone have any tips of how to cleanse my body and get back on track with my cycle?
