Crazy raise and drops in temps

Marissa • Mama 🥰

Hi, I’m new to bbt tracking, only 2 months in. I’m wondering if there is any reason to case the almost full degree raise and drop for the past 5 days?

I temp at the same time every day (5:30 am) after at least 3 hours of sleep, using an oral BBT thermometer. I have not done anything different tracking wise this week. Any ideas ladies? Just curious because this looks so crazy.
