Age 35 – Partial Cycle
These are photos from a 35 year old woman who has had four vaginal births – the last child was born 11 years ago. The couple is trying to conceive a fifth child, so they took the photos because it helps them to determine when she is ovulating.
You can see that her os (opening to the cervix) is a slit shape, which is how the muscle resumes after having dilated during her vaginal births. Also, the diameter of her cervix is larger than of a woman’s who has never given birth.
Her average cycle is 30 to 31 days with a 14 day luteal phase. In this cycle, she ovulated on day 17.
Age 25 – Day 14
Clear, watery & slippery cervical fluid flowing from os
Age 35 – Day 16
One day before ovulation; os is soft to touch; cervical fluid is gelatinous and clear with some white streaks
Age 35 – Day 19
Two days post-ovulation; cervical fluid is scant, tacky & white
Age 35 – Day 23
7 days post-ovulation; os firm & closed
