Everything you need to know about your cervix

You might never see your cervix, but that doesn’t mean you shouldn’t get to know it. Whether you’re trying to conceive, choosing the right menstrual cup, or simply curious about your body, understanding your cervix is a game-changer.

Let’s break it down.

What is the cervix?

The word “cervix” comes from Latin and means “neck of the womb.” Anatomically, it’s the lower, narrow part of the uterus that connects to the top of the vaginal canal - think of it as the gatekeeper to your uterus.

Your cervix produces cervical mucus, which changes in consistency throughout your menstrual cycle:

During ovulation, estrogen makes mucus thinner and more slippery helping sperm reach the uterus;
In the luteal phase, progesterone thickens mucus and increases acidity making it harder for sperm to pass through.

This isn’t just clever biology - it’s your body’s way of managing fertility.

Where is the cervix located?

The cervix extends from the uterus into the vaginal canal. During menstruation, blood flows through a tiny opening in the cervix and exits the body via the vagina.

Cervical position varies from person to person:

Low cervix: closer to the vaginal opening;
High cervix: deeper in the vaginal canal;
Tilted uterus: cervix may point forward or backward.

Your cervix also shifts throughout your cycle - it tends to be lower and firmer during menstruation and higher and softer during ovulation.

How to find your cervix?

First things first: wash your hands. It may take a few tries, and that’s totally normal.

To locate your cervix:

1. Insert a clean finger into your vagina.

2. Feel for the vaginal walls - soft and ridged, like the inside of your cheek.

3. Keep going until you feel something smooth, firm, and round - that’s your cervix.

4. If you feel a small dip or slit, that’s the cervical opening.

Measuring your cervix height

Knowing your cervical height can help you choose the right period cup:

High cervix: 55 mm (2.25″) or higher - harder to reach, most cups will fit comfortably;
Average cervix: 45–55 mm (1.8″–2.25″) - cervix sits mid-vaginal canal;
Low cervix: 44 mm (1.6″) or lower - cervix is close to the vaginal opening, shorter cups are best.

Use your finger as a guide: if you reach your cervix at the first knuckle, it’s low; second knuckle, average; beyond that, high.

Cervix & fertility tracking

Your cervix can tell you a lot about your fertility. Here’s what to look for:

Tissue softness: Firm like the tip of your nose when not fertile; soft like lips during ovulation;
Cervical opening: Slightly open during ovulation and menstruation;
Position: Higher and softer during ovulation; lower and firmer during menstruation.

Note: If you’ve given birth, your cervix may always feel slightly open - that’s normal.

Tips for checking your cervix

Avoid checking right before or after sex - arousal changes cervical position;
Check at the same time daily (e.g. after a shower) for consistency;
It’s easier to find your cervix when you’re not ovulating;
Don’t stress, it takes practice!

Cervix & menstrual cup placement

Your cervix plays a key role in menstrual cup comfort and effectiveness:

The cervix usually sits above the cup;
If your cervix is low, it may sit inside the cup and that’s okay;
Tampons sit higher in the vagina, closer to the cervix; menstrual cups sit lower.

If you’ve given birth, your cervix may sit lower - pelvic floor exercises (like kegels) can help support cup use.

Experiencing leaks or discomfort?

Your cup may be placed too high;
The cervix may be inside or pressing against the cup;
Try inserting the cup lower in the vaginal canal.

If your Lunette Cup isn’t leaking, there’s no need to go cervix hunting - you’re good to go.

Not only women have a cervix

It’s important to remember: not all people with a cervix identify as women. Trans men and non-binary people may have a cervix and deserve safe, inclusive access to cervical screenings and healthcare. Everyone with a cervix should know how to care for it and feel empowered to do so.

Why cervix knowledge matters?

Your cervix is part of your body’s internal landscape and understanding it helps you:

Track fertility;
Choose the right menstrual products;
Spot changes that could signal health issues;
Advocate for your reproductive health.

Whether you’re planning to get pregnant or just want to feel more connected to your body, cervix awareness is powerful.
