Clearer tests in afternoon?

Ca

Does anyone have luck with clearer tests in the afternoon rather than with FMU?

I tested again this morning but the line is even fainter than yesterday’s 4:30pm test 😪 not sure what to think. Trying to not overthink it but I am worried about a chemical pregnancy at this point. It looks basically negative. Faintest line but can barely see it in the pic if at all. Buying a FR today.
