Positive OPK but no temp rising?

Molly
My OPK was positive on the 5th so my husband and I have been BDing this week but I haven't seen a temp surge like I have in the past when I've ovulated. It has risen a little in the past few days (.12) but before it rose .5 and more. Has anyone else experienced this or happen to know what might have happened? Trying to figure out if I actually ovulated or not.
