TTC and coming off pill

How long did you wait to have a menstrual cycle or feel like you're back on track after stopping the pill before it raised concern or you saw a doctor? TTC #2. Been off of birth control a couple weeks shy of two months. No "official" period. Had some very light spotting two weeks ago. Two weeks before spotting I had very watery-slippery cm. Not pregnant and still no period. I ordered opk but it's not here yet. I got pregnant immediately after stopping the pill with my first baby. Just kinda concerned. I need opinions and thoughts.
