This chart shows a healthy cycle without conception. Remember every woman is different so you could have a perfectly healthy cycle even if it looks a little different. This woman had unprotected sex during her peak fertility, making her chances of getting pregnant very good. But with a thirteen-day luteal phase, it is apparent that this woman did not get pregnant this cycle.
What is going on in this chart?
1) Increasingly fertile cervical fluid as ovulation approaches.
2) Unprotected sex during the time of peak fertility, while the cervical mucus is very fertile, and before the temperature rises.
3) These higher temperatures indicate that ovulation has occurred. Her luteal phase was a healthy 13 days long. However, conception did not occur in this cycle.
