It's normal to pick up the LH surge for up to 2 days. They will pick up the first presence and all the way up to when the Lh starts going down and ovulation then occurs. You can ovulate usually 12-24 hours after it first picks up the surge. So I would BD when you first get your positve OPK, and they say if you really know your cycle, start even a couple days before you expect it, as sperm can live up to 5 days and egg only 12-24 hours. And I've read that going by an OPK is more accurate than bbt. I've read that your temp will rise before your LH surge and that's why isn't not as accurate. It's hard to know for sure when ovualtion actually occurs after they pick up the surge, thats why it's good to cover all bases to give pregnancy a good chance of happening in the month. They say every other day from like day 10 to whenever you ovulate is a good way of being sure, but if you know your fertile timeframe that's even better.
