Is this normal? Cd 12 Clearblue OPK says high (flashing smiley) but temp dropped?

Wondering is this normal. First time tempting. I took a Clearblue Ovulation test and I got a flashing smiley face this morning for the first time this cycle...Yay!....but my temp was 96.48?...before they had been in the 97's. First time my body came on menstrual after being on provera and clomid for 2 cycles.
