I know this might be silly but does it matter if i test in the morning or evening?

You should test in the afternoon because that is when most women get their LH surge. It builds throughout the day. I test between 5-5:30pm. It's helpful to test 2x/day when you get close to O time!

Not a silly question at all! The peak time to test is 2-4pm. My tests always worked anytime between 10am-6pm. I've even tested later than that. It's just best not to use FMU. LH metabolizes later in the day, so your results with FMU may not be accurate. Whenever you test, you want to hold your urine for as long as you can. At least 3 hours is usually okay, without drinking much during the wait.

I always peed at 3pm and then stopped drinking anything. And I would test when I got home from work at 6pm. I never missed my surge doing it that way. However, some women have a short surge and test mid-morning and afternoon.

I've gotten positives at all times of the day. The manufacturers do recommend not using FMU, but I have gotten positives with it. You should catch the surge if you test mid-afternoon every day, unless you have a super short one.

Thank you for the help. I tested today for the first time at 6 and -. I will try again tomorrow I guess at the same time?
