I don't track my BBT

❤️Amber • Mommy of a 12 year old, 3 angel babies and TTC
I don't track it everyday but I have been taking it here and there the other day it was 98.20, the next day 97.97 and two days later (today) it's 98.58. Is this promising that I may be pregnant? I don't know what the different temps mean according to glow in 9 DPO but I got my positive OPK Wednesday the 18th and I am 5 days till expected period.
