Positive opk morning- O or not?

[roraro]

Hi ladies,
Having a hard time interpreting whether I am ovulating and when. Have been ttc for almost a year now but my period was all over the place. Last cycle was 35 days, previous two were 28 days. This month I used the opk from day 10 and got negatives, until yesterday morning when the test line came up darker than the test one. Took it around 10 am but wasn't the first urine. Took another one in the evening but negative. Today, same story. Is it possible that the urine was not so concentrated in the evening and that is why I got a negative yesterday evening? I'm cd 21 today, bd on cd 19 and 20. What do you think, am I close to O or is it a false positive?

It sounds like it was probably o. Have you used opks before? I have had some cycles where I miss my surge because it was so short. Other cycles I get positives for 2-3 days.

If it wasn't fmu then I would say it is likely a positive and you should o 12-48 hours after that.

From what I understand with OPKs you're not supposed to use FMU. They're best when you test in the afternoon and evening.

I personally test with OPKs around 2 PM and again at 10.

Are you also temping? Your BBT will tell you if you O'd yet along with the OPK.

I have had a negative between strong positives and it's usually just due to diluted urine because I drank a lot in the hours before. This month I had a strong positive on CD13 in the morning, negative by late afternoon, then strong positive again the next morning on CD14 (O was later that day, it's super obvious to me when it happens so I always know anyway). If you got a positive, I'd take it as a pretty good sign that O is imminent in the next day or two.
