When to get off the pill...

Lindsay
Hi all! I'm getting married on September 2nd and would like to conceive almost immediately after. I'm currently on the pill and don't want to get pregnant until after the big day. We are spending a ton and I want to fully enjoy myself at our open bar 😉. My Gyno said to stop taking the pill a month before I plan to conceive to let myself have a normal cycle. I got on glow to track ovulation for a few months before I begin trying but from what I'm learning you can't even track ovulation when you're on the pill. Is that true? When should I get off the pill if I want the best chance of conceiving immediately?
Thanks!
