Age 24 – Most of Cycle
This is the cervix of a 24 year old woman with no history of STIs or abnormal Pap smears. She is sexually active and tracks her fertility using the Fertility Awareness Method; she and her husband use condoms during her fertile phase as birth control. This cycle is 25 days long, with ovulation around day 12 or 13.
Day 3
Some endometrial tissue (lining of the womb that is shed during menstruation) or a small clot leaving the os
Day 9
Very fertile cervical fluid that stretches a few inches between the fingers; egg-white consistency
Day 10
Wet & lubricative cervical fluid; os is slightly more open and central (and continues to be through Day 13), indicating peak fertility
Day 14
Based on a rise in basal body temperature and a general ‘drying up’ pattern of her cervical fluid, this woman identifies that she has already ovulated (likely on day 12) and is now in her luteal phase
