AF after BF for 12mo - when does cycle get regular?

[Dorasboots]

I've just stopped BF-ing DS, who is now 12mo. Had 1st AF last month, before stopping, but now on CD32 and no sign of AF. Thought was OV half way through month, but still nothing. DS not the best sleeper, so there's been no BD this month, so not expecting a BFP. We're "shall we, shan't we" about trying, so part of me is tempted to get on with the BD whenever we manage the energy, without the stress of wondering if it's the right time of the month

Does anybody know how long it takes for your cycle to get back to normal? TIA.

Stopped bf at 9 months, AF back at 10 months, cycle 35-45 days, only had three or four before getting pg again. Annoying as didn't know when ovulating and obviously was ovulating less frequently. No idea if this is normal.
