Can you not use it with your first bathroom trip in the morning? Like with a pregnancy test?

I would say to use first morning urine. The reason they want you to wait is so your urine isn’t as dilluted with fluids. I wouldn’t ba able to make it 4 hours, personally, but I’ve never used those things, so I can’t say for sure if you could go with less time.

I use mine when I get home from work around 7 pm, and I definitely don’t “hold it” for four hours 🙂  I tried it one cycle in the afternoon at work, and wasn’t catching the surge.  I only get positives in the evening.

I’m certainly no expert, but I have read a number of times that the hormone it’s testing for usually appears during the day, and that’s why you are best testing late morning-evening. I test when I get home from work at about 5.30pm.

I’d try to drink lots in the morning, go to the toilet at lunch, then try not to drink much in the afternoon so you can test. The main thing is that it isn’t diluted.

I’m blessed with a very large bladder, though, and can hold all day sometimes 🙂

I do fmu and then try to hold it again for as long as possible in the afternoon and kind of interpret from both since i can never make it 4 hours either

You could look into the Clearblue digital test (with the smiley/no smiley). You are allowed to use FMU with that test.

I used OPK’s and always tested btwn 5-6pm.  FSH tends to be higher later in the day.  I would drink 2-3hrs prior to testing and never had a problem.

If you’re using your FMU it’s not accurate.

I just waited as long as I could, I usually would try to stop going to the bathroom around 11 and then test at 2pm.

You don’t have to wait 4 hrs, just try not to drink too much in the afternoon so your urine is more concentrated.

If you are having trouble with your U being concentrated enough to register on the test, using FMU is fine… it just won’t be as accurate as an afternoon test (which shows an LH surge that started *that* day) because a morning test will only show a surge that started the day before.  So, long story short, while you can normally guess that O will occur 12-36 hours after your first + OPK, you need to figure 12-24 hours after a first + OPK taken with FMU.

Ughhh…I hated taking opk’s! The funny thing was that I was super dilligent in not peeing or drinking anything the first 8 days I had to take them, then on the 9th I said screw it and drank water, peed and got a +.

Maybe I’m lucky, but I never held my urine and I got positives each month I used the Clear Blue Easy digital. Granted, I wasn’t a huge water drinker until I got pregnant. I usually got positives in the AM and PM for 1-2 days each month. Good luck!
