OK - am a regular, but have namechanged as I have a few RL friends on here to whom I have posed the same Q, and I don't want them to know my MN nickname.
Anyway... I have ovulation pain right now - and have had since mid-afternoon. I think I'm right in saying that an egg lives for about 12 hours, and that it takes 12 hours for sperm to reach the fallopian tubes. So my question is, if we have sex tonight, will it be too late? Does the ovulation pain mean that the egg has been released? Or is it about to be released?
