TTC after Endo

Hubby and I are TTC less than a year after my first laproscopy to clean out my endometriosis. I stopped bc early June for the first time in most 10 years so of course I'm completely irregular. My last cycle was 21 days and who knows what this one will be. It's so hard pinpointing my ovulation because I've barely been off bc for a month but we are so excited and ready. I know realistically that we face some challenges with my endo, but any advice from those of you who got that BFP!?
