Okay, so from my research and asking, it's actually best to do the deed and make sure sperm is in there BEFORE you ovulate, so that would be before I get a smiley on my pink and white ovulation kit.
If this is the case, it begs the question really, what's the point in all these ovulation kits, because if I were to have sex when I got a smiley, apparently, it might well not actually work because it's best to have had sperm waiting before this period of time.
They are problematic - you can have an LH surfer without actually ovulating. Also, many women do in fact ovulate the day the surge starts, so for them it would indeed be better to have sex a day or few before the smiley face
I think I read that the older you get the closer ovulation is to the lh surge. I'm 34 and always ovulated the day after my surge, confirmed by taking temperature. If you have sex on the day of the surge you should be fine but, as the other poster says, you can use them to learn about your cycle and maybe aim for the day before the surge is expected too.
The problem is that some peoples surge only lasts for a few hours. So if you only test after work in the evenings and then ovulate in the mornings, you might miss the surge and not get a positive line. Other factors also affect them like the time of day you're testing and how dilute your urine is.
They cannot be used to confirm ov alone. They're best used to compliment fertility awareness, so use alongside temping, cm monitoring etc.
Personally I don't like them, used them for six cycles and have found they cause more confusion and stress which overrides the benefit. See how you get on with them but bear in mind they don't work for everyone.
Yes it wouldn't be healthy to avoid fluids to take a test in this weather! I'm not using them this month either, hopefully I'll be more relaxed but I can't stop temping as I'll be stressing out with wondering whether or not I ovulated
You're so young and you've got years ahead of you for falling pg. Leave the stress of scheduling to us oldies who have no choice but to be a bit more proactive with what time we have left!!
