How long does positive OPK result last?

I have varying results with OPK's so I am wondering what is going on.

Basically I am after feedback on how long people experience a positive result for OPKs?

But for those with a bit of time to help a crazy person out...here is the long version! :-P

I started out with no second line, then recently have had faint second line. On Friday morning I did a test first thing which had a strong second line but since it was done first thing in the morning and subsequent tests were quite faint, I put this down to being concentrated urine.

I did 5 tests yesterday:

1. I tested in the morning (second trip to the toilet but I had not yet had anything to drink) and the result was faint.

2. I did a test at lunch time and the result was quite strong.

3. I wanted to see what impact diluted urine would have on my result so I did another test an hour or so later after drinking a big glass of water and it was quite faint.

4. & 5. I did another two tests without trying to dilute or have concentrated urine and they were both faint.

If anything, I expected a strong result for No. 1 due to concentrated urine but this was faint. I can't explain the strong result for No. 2 unless it was actually a LH surge...However, I was expecting that if this was the case No. 4 & 5 would have also been relatively strong too?

Could No. 2 have been a false result or is it possible to have the LH surge only for a couple of hours?

I would say you had your surge at test number 2 - lunch time. Generally speaking, you won't get your LH surge over night, so the morning is likely to be negative. The lunch time one makes sense for the time of day, and had you not drunk alot of water and waited only one hour, your afternoon test would probably have been positive also.
Numbers 4 and 5, when did you do these? And how much water had u drunk?
In answer to your question, my positives last.about 12 hours. Mine start to get darker for about 12 hours, then stay positive for another 12 hours after that, then they fade out again.
I'll try upload a photo of my last two so u can see original.gif

Thanks so much Sturmy for your reply and sharing your tests with me.

Number 4 and 5 were done in the evening (about 5 O'clock) and late at night/early morning (approximately 12:30am) after coming home from a party. I had not had much to drink immediately prior to the tests (within a few hours I would say). So I am pretty confident that these are accurate.

My tests today are fading out quite a bit so it would seem that I did have a surge and that it was quite brief. I was concerned how brief the surge was but after consulting Dr Google, it seems that other women have experienced this.

Thanks again, you put my mind at ease!

As it is my first cycle off the pill, I would be very fortunate to ovulate so early (I was expecting my cycles to be very long!)
