After six months of this, still learning.
I’ve noticed that my LH surge may only last for 24 hours. Last month, got a positive opk (digital smiley in the morning) and a postivie wandfo in the afternoon. The next morning, no digital smiley. Does that mean that I ovulated the day OF my surge? Because the day after the positive OPK the LH surge was apparently over. Or, do you ovulate AFTER your surge is over. There’s always the possibility that I surged and didn’t ovulate. I got AF exactly 14 days after the positive OPKs.

This exact same thing happened to me this month and I asked the hive and they said you O after your surge, so if we got a smiley or peak then the next day we would O and the egg only lasts about 12-24 hours. So we DTD the day we got the smiley and the next day….hope this helps and good luck!!

Thanks! The main thing I am wondering is if your LH surge is supposed to last until after you O.

@winniewolf: I’m definitely still trying to figure all this out too, but I think the LH surge is only just before you ovulate…Once you ovulate, the opk’s don’t detect a surge anymore because it’s just prior to…It’s all so confusing;)

You are “supposed to” ovulate within 12-36 hours of first detecting your LH surge, then the egg is “good” for 12-24 hours. The surge is just a detection of the hormones that “tell” your body to release an egg. LH surge length varies from woman to woman, but most women have a surge of about 24-36 hours.
I generally get + OPKs all day the day before O (CD O-1), and sometimes the morning of O, but my OPK results are mostly negative (fading out) on CD O and CD O +1.

This helped me understand. The LH surge is really quick…

Thanks ladies – this is helpful. I was trying to figure out if a “short” LH surge of 24 hrs is a red flag. (The OV tests say to DTD 24-48 hrs after you get the LH surge…but for me I think waiting that long is just waiting too long).
