How few days post O is safe?

We are completely positive I ovulate Sunday. All the signs were there and months of charting says I O precisely every 4th Sunday.

So my OvuView app tells me it's not safe yet and I get why, but I'm having terrible reactions to condoms... If you are super regular, is 3 high temps enough?

According to TCOYF, after 6pm the third day post-O is considered safe. So if you o'd sunday, that would mean your first hightemp was Monday, so you would be safe tomorrow after 6pm.

Thank you! My book was MIA, just found the toddler had stashed it among the couch cushions ...
