LH surge but not O for days?

Jennifer
Hey all, I'm looking at old months temps and I'm wondering if it's possible to get a positive OPK but not actually ovulate for days after. I have a month in particular where I got a positive opk but my temp didn't rise until 6 days later. I ask because my temps this month look similar. I've had the blood test before that confirms I have O'd so I'm just confused. Thanks!
