Did you know that during the fertile period, the uterus adapts to receive the sperm and thus enable fertilization? Yes! Our bodies are intelligent in all physiological aspects. The cervix is an extension of the uterus1 that has a small opening. We can say that the cervix is an extension of the uterus, but thinner. At the end of the cervix, there is a small slit through which all external fluids enter and, most importantly, leave the uterus. A good example of this outward flow is, of course, menstruation. However, an open cervix is not the rule nor a constant throughout the cycle.

This is because, during the rest of the menstrual cycle, the uterus remains closed, that is, covered by a kind of thick mucus, called the mucus plug2 that is expelled very close to certain periods of the cycle. There are two situations in the cycle where the cervix remains open for a period of time—aside, of course, from labor. They are:

  • Menstruation: to facilitate the exit of accumulated blood from the endometrium (fresh blood or clots).
  • Fertile period: to facilitate the entry of sperm.

The entrance of the cervix looks like dimples, which, when closed, become narrower with folds around them. When open, it becomes wider and smoother. During the fertile period, the cervix remains open for about 3 to 7 days. This is all due to the increase in LH present in the body at this stage of the cycle. So, we can say that YES, an open cervix is a sign of ovulation, of the fertile period, but it may also be a sign that menstruation is on its way. The great difference between them is the stage of the cycle in which they happen. When it’s in the middle of the cycle, it’s a sign of the fertile period; when at the end, a sign of menstruation.

Even though the sperm is microscopic, it can make its way even if the cervix is closed; however, when it is open, it makes it 100% easier for the tiny cell to overcome the barrier of the cervix3. That’s why if you are in the fertile period, even with the cervix closed (which can happen), you are still susceptible to becoming pregnant.

Is It Possible to Identify an Open Cervix?

To identify if the cervix is open, you need to know and recognize your own body. Women who frequently explore their intimate area can more easily identify these changes in the cervix, when it is open or closed. There are several techniques, but if used, they require a lot of discipline since there is a risk of introducing infections if done improperly.

A small scratch with your nail and that’s it, you can trigger an inflammatory process. It is possible to check at home, using clean surgical gloves. Squatting in a crouched position, insert two fingers until you reach the cervix. It is also possible to see the cervix with a mirror, speculum, flashlights, and lubricating gel. This process is simple but also requires certain precautions when performing it.

It is also possible to check through a clinical exam at the doctor’s office. This is actually the most suitable method. A trained professional can check whether the cervix is open or closed and thus determine if the woman is fertile. An ultrasound can also show an open cervix, but this method is not the most common for this diagnosis, only for those trying to get pregnant, since it requires a transvaginal exam. The most recommended method is the clinical touch technique.

Take very good care of your body; remember that it is your most precious asset, and risking your intimate health is not a good idea—especially if you are already pregnant. Touching can induce miscarriage if done indiscriminately, okay? Good luck!
