Adjusting temp?

Em • 34 yo Mom to 12 yo sonshine. Living my dream and loving it. 🌸

I recently heard that Fertility Friend has an option to adjust your temp if you charted it at a time that is unusual. Previously this month on days I missed my time to temp I didn’t input at all, just left that dotted line 😑

Early in morning I got up, went pee and tucked in my son after falling asleep on the couch to a movie last night. I didn’t realize til I grabbed my phone it was 5:30am, when I typically temp. I went back to bed and temp’d again when I woke up, about 1.5 hour later. I tried the adjustment and FF and it said my temp dropped from 98.6 to 98.26. It seems about right from the last couple days temp. Just curious if anyone else has used this as a fallback and what their thoughts are on accuracy.
