Do you ovulate once the line on Opk has gone or before?

[keepthefaith]

Just wondered as I get a fade in for good few days so can see a positive for over 24 hours most months. Do you ovulate when line has gone? Got myself confused over whole thing!

We just had an attempt last night as test was positive and this evening it's still positive! Wondering when I should be expecting opk to be negative and if thats when ovulate?! X

the tests detect a rise and fall in the LH surge. usually within 24 hours of the first actual positive you ovulate. When the surge declines thats when the line fades and then goes away. Everyones pattern will be different. Mine faded in for 2 days, was positive for 2 days, then 3 days of fading away to 0.

When did you have your attempt that was successful based on your pattern?

Ps I know timing doesn't sway just curious!

Totally changes from month to month. Sometimes I O the same day as my first positive, sometimes I O the next day and the OPK has gone negative, or is still positive. Sometimes I O the day after THAT, and again, I've had OPK be still positive or be negative. I'd say it's 50/50, I.e about half the time I O during my surge, half the time after my surge has dissipated. It's very unpredictable for me. Thus why I temp!

THere is no exact correlation between when the OPK goes negative and when you ovulate. You will ovulate between 8-48 hours after the first positive (most between 24-36 hours after first pos), regardless of how long they stay positive for. The exception is if you had a bit of a false surge to start with, then a real surge right on top of it and it can maybe last longer than 48 hours before you O.

THe rate at which the OPK goes neg has to do with how much LH your body made and how long it takes to clear it. Nothing to do wtih when you ovulate *unless, as I mentioned above, the first surge was a false one

This is the issue I'm currently having. TTC pink, so I'm shooting (or at least my hubby is for just one attempt. We BD'd on Sunday when I first tested positive, but today is Tuesday and have an even darker line today. This is my 5th month of TTC and I just turned 39, so no time to waste. Atomic, what do I do??

Uschi attempt again on Thursday which could very well be O day. If O turns out to be Wednesday you had it covered from Sundays attempt

[maidentomother]

Uschi, BD again on Thursday in case you don't O for a few more days. By having 4 days in between your attempts, you will still have only one attempt in your fertile period, regardless of when exactly you O.

Are your cycles regular? How long are they on average?

Hi ladies,
Thanks for help. My cycles of late have ranged anywhere from 25 to 29 days in length. Last period was a textbook 28 day cycle with 14 day LP.

BTW, haven't set up a signature, but have two boys, ages 1 and 2. Going for third and final attempt at girl!
