Erratic BBT and OPKs, So confused please help!

First I apologize at this long question but I'll do my best to get my point across... Yesterday CD 15 I got my + clearblue digital opk, but a negative cheapy. Today CD 16 I got a + cheapy but a negative digital opk (both FMU), also my bbt was 96.81 at 6am but 97.40 at 7am! What data do I enter? Please help! If I take the higher temp that could be my spike and perhaps i already ovulated?
