You can identify your fertile window by internally feeling your cervix with a finger when observed in conjunction with daily Basal Body Temperature (using a Basal Body Thermometer) and Cervical Mucus (CM) patterns. It will change texture and position throughout your whole cycle!
How does it work?
The cervical os (cervical opening) is located in the back of the vagina at the bottom of the uterus, where cervical mucus and menstrual blood flow out. Your cervix is naturally somewhat low (about one finger-length inside your vagina) and has a hard texture, comparable to the tip of your nose.
During your menstrual cycle it will be very low, closed and dry, without any cervical mucus present. As you reach ovulation it will rise, become softer in texture and open up, allowing you to observe cervical mucus. This is your most fertile time! The cervix will lower back down and close again once ovulation has taken place.
Cervix Check Steps:
- Always be sure to wash your hands very well before internally feeling your cervix, as infection could easily be introduced to your reproductive system. If you currently have a yeast infection, or any other vaginal infection, wait until it is away before internally feeling your cervix.
- Get comfy… Sit on the toilet, squat or put one leg up on the edge of the bathtub. Take a deep breath, you won’t hurt yourself.
- Insert your index or middle finger into your vagina and slowly slide as far as your finger will go.
- Write down your observations – How far inside did your finger go? Did it feel hard, soft? Open, closed?
Check your cervix position at the same time each day for accurate observations and keep in mind that not all humans will follow this exact pattern, as each individual is unique. For those who have given birth, the cervix may be softer in general throughout each cycle.
Retroverted Uterus (Tilted or Tipped Uterus)
If your uterus tilts backwards (away from the bladder), rather than forwards, you may find that it is easier to find your cervix near ovulation and harder as menstruation arrives.
- In most cases, a tilted uterus will not cause any issues during pregnancy
- Some may experience painful sex
Chart your cervix flow for at least 3 months to use as an accurate indicator for fertility charting.
