Heyya! I hope you're doing good. Yes, women can ovulate twice in one month. Studies have shown at least two waves of maturing eggs in their ovaries in the same month.Traditionally, it has been thought that ovulation takes place only once in every menstruation cycle. You can go to OPK for a test. Yes according to a 28-day cycle, ovulation occurs before 14 days. I hope that this helped you. Good luck!
