LH surge at night?

[Girlswaylondon]

I usually get my positive opk CD 17 (tomorrow) I tested this evening just to be safe and it’s so close!
My question is, could I have my surge over night? Would this mean bding tomorrow night would be too late?!

It's possible to surge overnight but usually LH peaks in afternoon/evening. An attempt tomorrow wouldn't be too late since you probably won't ovulate for another 12-36 hours after your LH surges. Good luck!

Thanks, ksmom!

I’m being paranoid and thinking maybe I’m an overnight surger so I’m missing my window and that’s why I haven’t concieved so far!

LH reaches a peak in the wee hours of the morning (just before dawn) so usually this comes out in your urine mid-day which is why we test after lunch. It's possible but not very likely at all.
