Newly TTC

If I stopped taking my bc roughly 3 weeks ago how long will it take for us to be able to conceive? We have BD around 12 ish times since stopping BC but I haven’t had a period since before our wedding In June... I think they may be irregular because my body is adjusting to being off the pill. I’m just anxious and we are so ready to have a baby! Also it’s been very hard to track ovulation days because of the absence of my period. Any advice would be great! Thank you!
