We started TTC#2 as soon as AF returned. It was a couple of months earlier than planned, but we didn't want to give my endo a chance to grow back. I used OPKs and charted temps, starting from the 3rd PPAF. When I started charting, I found out that I was Oing late and had a short LP, due to the BF, which meant our timing had been wrong the first 2 months. We got a BFP in the 3rd cycle of charting, but lost the baby due to chromosomal abnormalities. I haven't had another BFP since and had a repeat lap in August (which, thankfully, showed just a small amount of endo re-growth the 13 months since my first PPAF).

Unfortunately, I also have DOR, so we're fighting an uphill battle to catch the right egg. I think the DOR is playing a bigger role in our IF at this stage since the endo seems to be well under control. If you still have a decent ovarian reserve then you should have a good chance at a BFP before your endo grows back.
