Long menstrual cycle

A long menstrual cycle does not imply any problems. If you have a long menstrual cycle, you have your period more seldom than many others. You may get your period every fifth week, while others have their period every third or fourth week. Many regard this as an advantage. If you have a long menstrual cycle, you also experience ovulation more seldom than others. Your ovulation occurs every menstrual cycle and, if you have a long cycle, longer time will pass between ovulations. When your menstrual cycle is long, you will need to consider that your ovulation will occur later than “normal”.

If you have a menstrual cycle of 28 days, you will ovulate approximately in the middle of the cycle. The ovulation occurs about 12-16 days prior to the next period, which means that with a 28-day cycle, ovulation occurs approximately 12-16 days after the first day of menstruation. If you have a long menstrual cycle, the ovulation still occurs about 12-16 days before the next period. This means, that if you have a menstrual cycle of 35 days, your ovulation will occur 19-23 days after the first day of menstruation, i.e. on day 20-24. This means that you can become pregnant about three weeks after the start of your menstruation.
