sperm meets egg

well had a weird evening last night..cd 13...since i have been opk'ing i have always go the smile on cd 13...well when i tested at 405...there wasnt one...........i was like what the heck? so when we put our 9 year old baby..lol...to bed...830....i took another...and i got the smile.......so either its because i went to the bathroom at 345....alot....and then took the test 20 mins or so later...or my surge just began....needless to say dh fell asleep!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! but at 130 he woke up and we bd......so does that bd count as doing it on a surge day?sperm plan says do it surge day, plus 2 days in a row..............any advice welcomed!
Answers:

When you have a surge it takes a few hours for the LH to make it into your urine. The box says to test in the after noon because most women have their surge in the morning, and it's afternoon before it can be detected. You could have just started your surge later in the day that day for whatever reason, and it didn't make it into your urine until later...or you could've pee'd alot...That's why we OPK! It's an inexact science...


yes..take it when you can get it...i just read an interesting article...she spoke about multiple positive opk's....and stated in that case...if that were to ever happen to anyone..they are probably o'ing later than they thought.......interesting...thanks for the feedback girls....i wish we all lived in the same city.......not mine though..we are #2 in the us for snowfall this year! yuck!
