Yep like has already been said everyone is different... I was pregnant 2wks after stopping bc! But I had only been on bc for less than a year and for most women the time they've been on seems to have some effect on how long it takes to get 'back to normal'. If you've already had a few af then its probably gonna even out fairly soon and even if it doesn't get to a standard every month doesn't mean you can't get pg! Charting with FF is probably a good idea though, or even just checking out the fertility signs course so you'll have a really good idea on what to look out for. Hope you get bfp soon!
