Any cycle buddies??

Im CD 13, I.got my 1st positive lh strip today at like 6am, but tested again a couple hrs later and had a PEAK already? Will that make my fertile time shorter? I usually get a surge on CD 13 and get a peak the NEXT day.. Im wondering if I still have 2 days to get it on. My partner is busy with his mom today so, Im feeling like we cant wait until tom to have sex... I read after a surge, u ovulate anywhere from 12 to 48 hours and after a peak, its 8 to 20 hours..I know I have at least 12 hours after my egg drops but I feel sooo edgy ..I dont do everything I do all month to waste my fertile time..uggh.
