really short LH surge

[Scout8601]

I'm wondering if anyone else has a really short surge.  I'm also wondering if that means anything.  I use the CB digital OPK.  I tested yesterday around 5 pm and it was negative and again about 9 pm or so and it was negative.  I tested this morning around 7 am and it was positive.  Then just out of curiosity, I tested this evening around 6 pm and it was negative already.  I'm glad I tested more than once a day or I just might have missed it.  But has anyone else noticed that they have this short of a surge.  And also, since it's back to negative does that mean that ovulation has occured already?  I'm still have a bit of cramping that I thought was ovulation cramping, but then again I've been cramping for 2 days..it was worse earlier today, so maybe that was when I ovulated?  Just trying to figure all this out.

All the LH surge is, is your body telling your ovaries to release.  That release can happen anywhere from 12 hours to two days later.  So your surge could be over an then you ovulate a day later.  It's all very confusing!

If you're also temping you can use that to gage your 'window' of ovulation.  For example, if your LH surge happens on CD10 and your temp rises on CD14, then you can deduce that you ovulated somewhere between CD11 and CD13.

Best of luck, I hope this helped!!

I think it's possible some women only have 10 hrs per month where they can conceive. I am in the same boat as you. I got a positive serge the other day and for past 24 hours have had cramping  not exactly sure what that is all about
