Third month TTC. What should I expect and when to test during wonky cycles?

It's our third cycle trying! I'm excited because we've been having a lot more sex this month. 
Here's what my cycles have looked like so far:
1. Ended the pill the end of feb. Got an extremely heavy period right after. 
2. First cycle seemed a few days late (I forgot to look at cycle length before
Posting this). I had a few weird symptoms but I think I was so excited I was symptom spotting. 
3. 60 day cycle. I didn't think my period would ever come. 
According to the average cycle thing on here it's saying now is my fertile window. I was tracking my bbt for a few days but my sleeping schedule changed and I forget when I roll over. But my cm is saying that I probably am ovulating around now. 
So I'm curious when people have wonky schedules when do they test? I've read that birth control can take about three months to get your system on track. Anything I should expect for month three? I can bbt test again.
