Hi all im new here,
I bought an ovualtion kit and i got a positive LH surge on day 14,
I did a cycle chart and it said the 3 days before ovualtion were fertile days, i thought you were supposed to do the deed once you got a positive LH surge result?
So whats the best time before the positive result, on the day you get it or after?
The reason i ask is my Hubby and i are limited to one try, two at the most, so we have to be precise as we can, we also are doing ivf next month again.

Also how long should a positive LH surge stick around on a opk?
