I didn't read your other posting - but it helps if you know how long your cycle is and whereabout in the cycle that you are ovulating. In a 'average' cycle of 28 days, you would ovulate at around day 14 -so have sex just before and durig that day. I have just starting to 'temp' so that I will be able to tell when I am ovulating or not........checking your cervical mucous and the consistancy also helps - read some old threads to get some tips
I would think that if your periods are fairly regular, have sex every other day between day 10 and day 16 to cover all bases. Good luck!
