TTC while breastfeeding

Hey there! 
I am new to Glow and I'm looking for some insight & support here!
I am 6 months pp and ttc #2. I am still breastfeeding ds and I have not gotten AF since before he was born. 
When did you finally get AF while nursing? Also, how are you tracking your ovulation if your cycle is all crazy? 
On top of this...I also have PCOS and got pregnant with my son using fertility treatments. Ugh! So many variables and its stressing me out lol. TIA 😃
