TTC with very long cycle

Anyone else TTC with a long cycle? My last cycle was 47 days! Stopped taking BC pill in March. Started trying a few weeks ago. I never knew there was such a short window of time in which you can conceive (3 or 4 days?). I’ve spent my entire life fearing an accidental pregnancy but now it seems like it’s very hard to conceive within just a month or two. With my cycle being so long now it seems like it’s going to take quite awhile.
