I know you're supposed to do the CBC with fmu but are you also doing the paper tests with fmu? I ask because these are intended to be taken about midday and should be taken at the same time every day you're testing for the most accurate results. Sometimes people will test multiple times a day but start at noon and then another around 4 pm and maybe even 8 pm if the test is super close to positive. I never temped so I am not super helpful there.
