BBT tracking?

McKenna • Momma to 3 kids 💙💙💙(👼) pregnant with our 🌈, HG survivor.

I just bought this thermometer to start using next cycle. My period is due in 2 days and I just feel out. We’ve been trying since losing our son at 17 weeks in November. No luck yet with just using OPKs, so I thought I’d try this to.

Any tips and tricks? Is this a good thermometer? I know nothing about temping.
