I physically can't BD another day, so I am hoping the answer is "I am now in the 2ww!
Thanks! |
You would estimate 24-36 hours after the first pos OPK where the line is dark or darker then the control line. So, if your darkest + was on CD15, assume within 24-36 hours from then you'll have O'd. If today is CD18, you're good. But, I will caution you that a positive OPK doesn't necessarily mean you've ovulated.. sometimes your body tries to ovulate, and it releases LH, but for some reason the egg doesn't release.. your body generally will try soon again after its first attempt until successful.
The only way to truely nail down the 'day' that you ovulated is to combine using OPK's along with temping your basal body temperature. With this also you know how long your luteal phase is (time period from ovulation to period). Both methods combined will give you a lot of insight in your own cycles!
It's fairly surprising the things you can learn.. because of my charts, my doc was able to pin point a thyroid problem, and apprximately WHEN it occured.. she could also differ that it was getting better.. all that from my temps! Very helpful for many reasons lol.
