Basal body temperature

Vanessa

Hi there. I am 4 weeks 5 days. I am very excited and nervous about my first pregnancy!

I have stable and high bbt in the past few days. but today it goes down by 0.1 to 36.89. Is it normal for the bbt to go up and down slightly even getting positive line?

Thanks. Bless u all, moms-to-be.
