Cb advanced digital ovulation tests - morning or evening

[Sharnie44]

I have just done my first cb test and got the circle which is fine as I no it reads first result as a baseline for the rest but I'm reading a lot of mixed reviews on whether to do it with fmu or do it at night. Does anyone have any experience on what time of day is best.

I always do in the morning as instructed and it has been working fine. I also test later in the day with cheap opks and the two always accurately reflect each other

The instructions clearly say first morning urine so that's what you have to do. Once you have the flashing smiley you can test more than once a day if you wish.
