Based on my first two pregnancies I would have answered that pg cycles usually get higher temps. For example, I am usually in the low 98's during my LP, but with my first two pregnancies I bumped up into the mid-98's and a few even higher than that.
But, the third pregnancy did not follow that pattern at all. I kept thinking AF was coming b/c I dipped below the coverline more than once and my temps were only in the high 97's with one or two in the low 98's. I really had no idea what was going on and started to question my ovulation day. But when AF still hadn't come after 20 days from when I (and FF) thought I ovulated I couldn't ignore it anymore and tested. BFP. Once I tested positive, FF redrew the coverline.

How many DPO are you now? 12? Some women get a BFP on day 12, but I personally like to wait until I'm several days past my longest LP so I don't get ambiguous results.
