BBT too low?

jas

This isn't a full cycle yet, and it's my first time charting bbt. I'm curious if my follicular phase temps are trending too low (96.81-97.50) or if i'm just being paranoid. My ovulation dip was clearly on Dec. 2nd and temps are now trending upward (97.73+). My research is showing anything below 97 degrees in follicular phase is too low and I should be in the 98's post ovulation. I'm pretty close but just below. Opinions?
