Having worked as a nurse in the OB/GYN field for 20 years, one way to try without even using ovulation sticks is to count the first day of bleeding as Day 1 of your cycle, then start having intercourse on days 10, 12, 14 and 16. Most women have a 28-30 day cycle and following this schedule, you should catch ovulation when it occurs. Good Luck!!
PS - having sex every day decreases the sperm count and lowers your chances of conceiving......sorry guys ;-) 4951
