I usually O 48 hours after my last positive OPK. You're almost certainly not out.
Really? I guess I am having a brain fart because for some reason I thought it was 12 hours. Good to know, thanks!!!
It's 12-36 hours. That said, this month I got positive OPKs for two days after I ovulated, so...go figure. The point is, you just need to bone when he gets home.
