how long until you got AF after getting off BC?

Th
Ughhh. I am CD38 after my withdrawal bleed and patiently waiting for either my BFP or AF. Preferredbly BFP but at least if AF comes I can start really figuring out my cycle. I've only been trying since feb 10th. I know, I know, it's still early. But it is definitely annoying waiting. Anybody else have this issue? How long until you finally got your first AF after your withdrawal bleed?
