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 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 in her luteal phase.  This cervical fluid is sticky and white and typical for her in her luteal phase.

Day 23

Her luteal mucous is white, sticky and does not stretch.  You can see that it dried in her panties in streaks, indicating that it does not contain much water and is therefore not fertile.
