Does this look a bbt thermometer cause I check my temp and it say it was 98.3

If theres only 3 digits then its not a bbt thermometer. A bbt thermometer measures like this. 98.37.

That's what I used when I was pregnant with my son

A yr ago I was and my cycle was six weeks late

It’s got to have 4 digits because the temperature will vary by small amounts that won’t show with the 3 digit kind.

Not a BBT. But I haven’t ever used a BBT. I can still clearly see my shifts
