The high temp was just a fluke. I would keep BD daily till you're certain, it doesn't hurt and may help.
O pains are not terribly useful unfortunately, because you can have them before, during, and after O. Usually once they're gone for good, it means O did happen at some point, just that we can't know exactly when, and even if they're still there, it doesn't mean that you haven't Oed yet! So confusing, I know!
