Odd opks...

I've been ovulating around cd 15 and usually start OPK at cd 9 and see a nice fade in. Yesterday was cd 9, took a test in the am (test says to use morning urine) and it was a positive. Thought that was odd, I got cramps on one side pretty bad later that day and had spotting ( which I've never had with O) so I took another OPK before bed and it was stark white! What's going on here? Temp this morning had not risen, going to go do an OPK now to see what's going on but I'm confused... (We're not trying btw, just tracking cycles )

LH levels fluctuate a great deal throughout the day, and it's very common for levels to be lowest late at night. Only ever compare OPKs taken at the same time of day, and only consider your darkest OPK of the day. What brand are you using?

Tested this am (cd10) and it was almost almost positive, or maybe positive it was so darn close. Still spotting.

Walgreens brand. I know I have Lh issues-- I was having a string of 4-5 + opks in a row around my period which concerned my ob and she ran blood work showing it was abnormally high for being so close to my period. So I'm going in at certain days of my cycle to test my hormones :( not sure what's going on. Next test at cd 21 so hoping that will give some answers. I was recently diagnosed hypothyroid and my endo thinks it's messing with estrogen/ progesterone/Lh/fsh balance :(

If you had normal hormones I'd say it sounds like your surge is fading, but check tomorrow am to be sure it is indeed. But if your LH levels are too high OPKs will not be reliable for you. Hopefully fixing the thyroid issue will return your sex hormones to normal levels.

So my opks are all positive in the morning, all negative in the evening, and my OB is having me test at 2 pm every day as that is supposed to be most reliable. My 2 pm test was almost positive yesterday so I'm thinking I will get a positive today.

Opks used to work great for means I even used them to detect O and avoid pregnancy, but when I started thyroid meds I guess that can interfere with estrogen levels which can in turn mess with lh. I'm glad I was using opks to see that lh was off, so now my endo is monitoring that too.

yes I think the afternoon/evening testing is most reliable.

Your body uses LH for lots of other things and sometimes it makes enough to turn a stick positive.
