Help.. been off bc since August

Okay at this point I need help.. been off bc since August and we still haven’t conceived. At first i was on it like a hawk , now I’m just like okay let’s not over think this but still nothing. I following my ovulation window on the app but like when is the best time to have sex? I tried the last 3-4 days up to ovulation. Should we try everyday after my period?? I know everyone body is different but what was some tricks you tried? I go to my doctor in May to reconnect but i need encouragement at this point and ideas.
