    cycles and ovulation
    invisbeth8182 posted:
    My menstrual cycles are different lengths each month and I never know when to start using the ovulation kits. I was originally told by one doctor that ovulation usually occurs between days 12-14. But I've heard otherwise that it depends on how long the cycle length is. I am currently menstruating (on day 3). My last cycle was 33 days long. Before that, 35, and before that it was 45 days long. So should I go by how long my last cycle was to test for ovulation? I've been trying to get pregnant for a couple years so it would be nice to hit my most fertile days. I'm also trying something new....using condoms during intercourse except for the days I'm ovulating. Please give me advice and/or suggestions.

    More than likely you have an ovulation problem. The ovulation kit should turn positive 14 days before the next period but you have to be able to predict the next period to be able to know when to look. When cycles are normal, most of the time, they are between 27-35 days in length (day1 to day 1), regular and predictable ( /- 1 day, for example 29-31 days or 32-34 days, etc.) and the luteal phase (time from a positive ovulation predictor test to the next period is 14 days. I suggest you see you doctor to try find out why your cycles aren't regular & he/she may place you on an oral medication that might help.
