Question about LP and temps!

I'm on 8DPO today (CD30 of a usual 28 day cycle).

This month FF tracked me as having a late O on CD22. Should I be expected AF 12-14 days from the late O date(CD22)? Or is that not how it works with O'ing late?

If it comes earlier does that mean a possible M/C? I'm Rh- so I have to be careful with potential chemicals etc as I need to get my shot to prevent antibodies.

I haven't tested yet as I don't usually get positive tests early. My temp dropped on 5DPO and spiked back up and has stayed high. I'm cramping like CRAZY which has been happening pretty much since O and CP seems high and closed... but I still doubt a BFP for this month so right now I'm waiting on AF.. don't know when to expect her! Any thoughts?

no that's how it works. LP is generally fixed, so if AF normally arrives 11 days after OV it means you'll have a longer cycle if you OV late

WSS^^^^ :)
