Low Grade Fever?

Ry

Hi! My normal BBT is around 97.5 and peaks to 98.5ish after ovulation. the past two mornings, my temp was 99.08 and today it was 100.09. My period is due in 4 days and other than my boobs hurting, I feel normal. Has anyone experienced this as an early pregnancy sign? DH and I were active during ovulation so there's a good chance I could see a BFP in the next week... 😬
