Polycystic Ovary Syndrome (PCOS) is a condition where a woman has imbalanced female sex hormones. This can cause long cycles, irregular periods, cysts in the ovaries and other health conditions. For a woman with PCOS trying to avoid pregnancy, it is important to understand that with longer cycles there may be longer fertile periods than someone without PCOS. By charting your fertility you can be sure that if you did not ovulate yet you could not be pregnant. So women with PCOS may have a lot of fertile cervical mucus but do not actually ovulate. If you are trying to avoid pregnancy it is important that you still use protection during your fertile time because ovulation is possible.
1) Long follicular (preovulatory) phase.
2) Unprotected sex during the first 5 days of the cycle, and in the evening of days when no cervical mucus is present.
3) Protected sex during the fertile window. From the first sign of cervical mucus until 4 days after the Peak Day, and 3 days after the temperature shift, she is considered fertile.
4) This sustained temperature rise indicates that ovulation has occurred.
5) During the infertile part of the luteal phase, she is considered infertile and is safe to have unprotected sex again.
