OPK time of day?

[Cadence]

Hi,
Just a quick question regarding the time of day you should test using opk's. I have read several times on this site that 2pm is the best time. However I have been using seretec lh tests (provided by Fertility specialist) and she said it is best to use fmu as the highest surge is about 5am?
Are all tests different, anyone else been given this advice?
Thanks

I heard the exact opposite advice, that LH is produced while you are awake. Infact I have never heard anyone advising to test with FMU!

Most sites say the best time to test is 2pm, I always tested between 4 and 5 pm and got good results.

HTH!

Ive never heard of 5am doing an OPK test before.....

OPKs measure LH in your urine.....and LH is not apparent in your urine till later in the day - thats why they say after 2pm. Ive had a +ve at 8pm though, and i have read not to test after 10pm, as levels drop......

Good luck.

I've also read that 2pm is the best time but I would tend to listen to your FS on the time that she recommends. It's going to be annoying getting up at 5am to wee each morning. Totally worth it though.
This could explain why I never ever got a positive OPK even the month that I conceived DD.
Best of luck getting your BFP!!!!

Thanks all!
Yeah I thought it was a little strange as it goes against everything I had heard. Having said that I have been using the opks for the last 2 cycles and haven't got a positive, mind you the fs thinks that is because I haven't ovulated!!!
I might ask her about it again next time I see her!
Thanks again for your input!

I've been researching and I take back my first post. Every single website says not to test with the FMU. Some suggest testing twice a day at 12noon and 8pm to have a better chance at catching the surge. They say just to try and test the same time each day and mostly say 2pm.

It's really confusing isn't it...

Having many long years of using them it took me a loooooong time to get it right. FS will recommend testing with fmu. The reason some companies suggest you don't is that we all have LH in our wee - even men! If you use FMU you are more likely to get a false positive - that is why companies suggest that you don't use FMU. (because FMU is usually more concentrated)

Having said all of that - I got positives with fmu that were the LH surge - and I needed to test often - I would get an almost positive at 8pm and (embarassed to admit) I would test at around 2am and almost positive - then a positive with FMU - then at 2pm I was back to two lines but not a positive. So, had I tested only at 2pm I would never have got a positive!

MY specialist also suggested using FMU - I was on clomid with trigger shots and used OPK"s for this as well and on the packaging it said FMU.

I know peeonastick the website says to test at 2pm - for me that didn't work. I needed to test frequently and sometimes I got a positive late in the evening - but mostly it was early morning,...

Good luck on your journey... Hoping to see a for you soon...
