Recently stopped birth control


So I recently stopped my birth control (2 months ago) for multiple reasons. My partner and I are in the mind set of if it happens great! And if not we will keep trying...I noticed that yesterday was the first time in a really long time that my CM had a Raw eggwhite consistency(and we spent the night together) and I also read that the patch actually prevents the release of a egg...I've been on birth control pretty regular since I was 14yrs..I'm curious how long it could take to conceive after being on birth control for so long and when would be a good point to actually start worrying..
