Question when is...?
my cycles are in the region of 25-28 days lets basically say 28
Answers: 2/20/08...3 days beforehand and 3 days after
Your prime conception time will be during ovulation which occcurs between day 11-14 of your cycle. You should avoid days between feb 17-20. If you are completely regular, you are most expected ovulating 14 days into your cycle. So, 3 days before until 3 days after time 14 are NOT safe times.
However, why verbs and use a condom? Protect yourself from pregnancy and STD's at the same time.
Be economically!
2/06/08 - First day of your cycle
2/17/08 - A little bit fertile
2/18/08 - Fertile
