I track my bbt every month for natural family planning. Usually my bbt is in the 98's before ovulation and then after in the 99's, but for some reason this month my bbt seems to be staying in the 99's right after my period. Is that normal? I also ovulated early or something this month, I think, from what I can tell from my chart and how I've been feeling. Just having a hard time reading this month since it's higher than usually so early on.
