Observing your cervical mucus

Observing your cervical mucus

You may have noticed that your discharge isn't the same from one day to the next. That's no accident: part of it, cervical mucus, changes throughout your cycle. Learning to observe it is a way to get to know your body better, with no device and nothing to buy. Here's how to do it, and above all what this observation can tell you, and what it can't.

Why mucus changes

Mucus is produced by the cervix, and its appearance changes with the hormones of your cycle. According to the NHS, around ovulation it becomes thinner and stretchy, a bit like raw egg white.

This matters because the time when pregnancy is possible is short. A landmark study published in the New England Journal of Medicine found that conceptions happened during a six-day period ending on the estimated day of ovulation. Sperm can survive for up to 7 days in the fallopian tubes, the NHS adds. And ovulation doesn't always fall at the same time: in most women it happens 10 to 16 days before the next period. That's why your body sometimes gives clearer clues than a calendar.

How it looks through the cycle

Cleveland Clinic, a major US hospital, describes a typical pattern over a 28-day cycle:

after your period: a dry or tacky feeling; mucus may be white or slightly yellow;
then: sticky mucus, then creamy;
around ovulation: stretchy, slippery and very wet mucus that looks like raw egg white;
after ovulation: dry, or almost dry, again until your period.

This is a typical description: for you, each stage may last longer or shorter. That's exactly why it's worth observing over several cycles rather than comparing your body with a diagram.

How to observe it

Cleveland Clinic suggests three simple ways:

look at the toilet paper after going to the toilet;
look at your underwear;
with clean hands, insert a finger into your vagina, remove it and look at the mucus.

A few practical tips: stick to the same method so you can compare day to day, and write down what you see rather than relying on memory. In Lovae, you can log it under discharge: none, sticky, creamy or egg white.

What can blur the picture

According to Cleveland Clinic, the appearance of mucus can be changed by:

breastfeeding;
lubricants used during sex;
hormonal contraception;
sexually transmitted infections;
other vaginal infections, such as thrush or bacterial vaginosis.

If your discharge seems unusual or bothers you, talk to your doctor or midwife.

What mucus tells you, and what it doesn't

Egg-white mucus is a marker: it suggests your body is probably going through the time around ovulation. It isn't a measurement. On its own, it can't show that ovulation has happened, and it isn't reliable contraception without discussing it with a professional, Cleveland Clinic points out.

On the research side, two US observational studies found that cycles in which women tracked their mucus, or other signs of their cycle, were more often followed by a pregnancy. In the first, only 6% of the 331 participants observed their mucus consistently. The second followed 5,688 women, 75% of whom used at least one cycle sign. These studies show an association: they don't prove that observing is what makes the difference. And the 2023 Cochrane review, which pools the trials, judges the evidence on cycle-observation methods as still too limited to draw conclusions.

Above all, you don't need to find "the right day". The NHS simply talks about having sex every 2 to 3 days. If observing becomes a source of stress rather than a help, you're completely free to set it aside.

When to talk to a professional

If your discharge changes in an unusual way, or comes with discomfort.
If your cycles are irregular or absent: the Assurance Maladie (France's national health insurance) advises seeking advice earlier when trying for a baby.
If you've been trying for 12 months without getting pregnant, or for 6 months if you're over 35.
