oh damn! I wrote a post and lost it!
It's frustrating not knowing your body and its cycle hey? I am going through the same frustrating thing. and not knowing if you are Oing or not. i believe if you are getting AF (even tho its irregular) then you are probably "O"ing at some point in that cycle but it may differ each cycle KWIM?
I've been off pill since Mid march so around same time as you so yeah just about 4mths now..
I'm not temping but i am charting on FF website and thats helping me i guess... we arent TTC until Aug/Sept though
