Can’t find right thermometer

Theodora • TTC # 1 IVF 🙏 Unexplained infertility/endometriosis

For some reason even if they had digital I cannot seem to find a thermometer that gives two decimal places. I do you have a digital one that gives one decimal place, would I be able to use that until I find order the one that I should be using? Can I put the data as in my temperature in to the app every morning even if it’s not Add to decimal thermometer?
