Hi there, I was on Cerazette for just over three years, with no periods at all.
Once I came off the pill last year, it took 28 days then I had a normal period, and we fell pregnant after a couple of months, so I was lucky in that respect. I would say that you have had a period judging by what you described, so looks like all is well with your body!
We are all different, but the only advice I can give you is start takinfg your folic acid tablets straight away, while you are trying for baby, this will help your body and baby in the long term.
I am back on the mini-pill again as I sadly had a mmc last October on the morning of our first scan
I have had normal periods since then, even with the mini-pill but it is a different brand from the last one so may be why.
We are currently thinking about trying again at some point soon, we were set against it after what happened last year, but would like to try again for baby number 2 while our little boy is still a young age (he is 4 this July).
Good Luck and hope you have some good news soon! xx
