26 cycle, 4 day period and very light always. when do i ovulate? my cm suggests that i ovulate just before my period. any suggestions?

14 days BEFORE: Ovulation occurs consistently about 14 days before your next cycle. If you know how many days there are from the first day of the bleeding to the next during your normal cycle just subtract 14 days. This allows you to predict when you should be ovulating.

Difficult to say: If your cycles are irregular, it is difficult to predict ovulation. We can retrospectively tell when ovulation occurred by counting back from your menses. Your menses will always start 14 days after ovulation. It is the 1st half of the cycle that varies. Of course if you are irregular, you may not be ovulating each month. See your gyn for an evaluation and treatment. Best of luck!
