When I came off after 5 years I had no change at all. My period kept coming regularly, except onche 3 months later, but other than that everything stayed normal. (Even though before the pill my periods went haywire quite regularly... -.-)
And aftwr 6 months I got pregnant :) That was our purpose tho :) I am right now in the 6th month :)
I guess it is different for everybody. I was afraid my periods would get crazy again, I was really happy it didn’t happen. Or maybe it would have happened later, had I not gotten pregnant.
