I am 7 weeks post partem tomorrow, I think I may be getting AF back!

i feel so cheated.
I guess its possible that its still a bit of pp bleeding but i doubt it, that stopped a couple of weeks ago.
(TMI alert), ive had loads of CM which seemed very fertile so maybe I O'd??
A couple ofdays ago I had AF like cramps too and thought oh no its coming already but then nothing until today. its only light at the mo but very AF like.
I'm EBF too. well i guess time will tell.
