I've only got a few cycles under my belt since coming off the BCP, 29, 25 and now 26 days.
I think this is right but feel free to jump in and correct it anyone, I'm still learning myself
Period on 9th October to 2nd November = 25 days
Period on 3rd November counts as calendar day 1 again
So if you have another 25 day cycle your next period would be on the 28th November.
Good luck TTC x
