What ovulation calendar did you use and did it work? - my ovulation calendar

My times are about 26-27 days. They differ each month. I have several online calendars and ovulation is the third month of the experiment for baby # 2 My husband and I are both healthy and take vitamins daily. I also had my daughter while I was on birth control, so I know you are fertile. Do you have an ovulation calendar, and it did not work. Please say no tests for ovulation. I do not want to spend money on them.
