I went off mine in April, had one REALLY long cycle (51 days), then two normal-ish shorter cycles (one 32 days and the other 35 days), and I got pregnant in August on day 25 of my fourth cycle off BCP. I wasn't TTC though, so it's possible I could've conceived earlier had I wanted to.
When I was TTC my son, it took 5 months after BCP to get pregnant. I was charting right from the start, and it looks like my first cycle was a bit crazy (late ovulation, short luteal phase, abnormally low temps), but they were pretty normal after that. Good luck!
I went off BCP at the end of July. I didn't have a period at all in August so I started fertilaid at the beginning of september to regularize me. I got my period a few days after starting and conceived in september - not sure when I ovulated, it wasn't on CD 14 though, it was later. We DTD every day in September to make sure we were covered.
I went off bcp Oct 2010 and didn't get my bfp until Sept 17th 2011. That was 11 cycles for me. My cycle lengths were all over the place for about 6 months before averaging out to about 33 days. Some were really short some long ranging from 25-36 days. My period length never went back to normal tho. It got super short about 3 days altho two different cycles were 1 day. i was used to 5 days.
Good luck ttc. Hope everything gets back on track for u soon.
My first cycle off bcp was the same as my pre-pill cycles. Then it got really dodgy from there! 2nd cycle was 73 days long, the next 63, the next 53 then I had a couple of 40- odd day cycles before falling pregnant and finding out on CD 73! I worked out that I must have ovulated on about CD 54- ish, which is insane! So after a year my cycles hadn't sorted themselves out but I did fall pregnant and am now expecting a baby girl in time for Christmas!
