Hi littlem, yes I've been in the same boat..story first then some encouragement :)
Had to stop Microgynon in Nov 2012 after 10 years, not because we were TTC but because GP thought I got migraines from it (not true btw). Went on Cerazette for a few months and stopped in April 2013 as we started to think about TTC. Got period after 4 weeks and then every 28 days like clockwork. They were quite light and not painful but I didn't think much of it as my 'periods' on Microgynon had been very light for so long. Then in November 2013 period was late and I thought maybe maybe maybe we had managed to time everything alright! For two weeks I started to get cramps, pinches, twinges etc, and then BAM - full blown period with cramps. I suddenly realised that this is what it used to be like before I went on the pill as a teenager all those years ago.
Basically, what I think happened was that for the first 6-7 months I did not ovulate at all, my body just kept going as it had for the past 10 years (obviously the few months on Cerazette didn't help either, horrible stuff). Then something clicked and it all started again. From then onwards I've been getting normal periods, they've been quite irregular 27-39 days, but seem to have settled back into about 28 days for the past couple of months and we are now actively TTC again :)
You are right about the doctors, all they will tell you is to wait and see. You can however ask them to do some hormone testing, to make sure your levels are normal, but then again, they might not be yet as its only been a couple of months since you came off the pill. If you go and claim you have some mild PCOS symptoms, they might also refer you to do a scan of your ovaries, if that would give you peace of mind.
BUT...I really think it might just take some time. I know its not easy, I've been there and done the panic bit.. Try to remember what your periods were like before Microgynon. Cramps, symptoms, heaviness, pms, etc etc, this is basically what you want to happen, this means you're back to normal. I started writing everything down so i could refer back to it, like symptom spotting but for periods rather than a bfp :)
finger crossed for you hun!
