How long after going off the pill did you conceive??

I'm 23 years old. Had my son back in June 2013. I went on the pill after I had him (Aviane) and have been on it ever since. Well I recently decided to go off the pill because me and my boyfriend want to try for our second baby. Stopped taking it at the end of July and have been pill-free since. My cycles are still regulating themselves (one month was 28 days, the next was 36, and this most recent one was 27). I don't really know what my cycles were like before I got preg last time because I never really tracked them. If i had to guess I would say they were around 30-35ish days ... I thought after stopping the pill that I would get pregnant immediately! But nope its been 3 months and still nothing 😕Any advice/experience would be greatly appreciated! 😊
