When do Women Ovulate?

For women, ovulation is one of the most important things to happen to their body each month. It’s a process that drives a lot of other changes in the body across a monthly cycle of 28-32 days that affects almost everything: it can cause pain, affect your mood, even your temperature.

Understanding when in the month a woman ovulates isn’t just the key to understanding fertility, it identifies the lynchpin of the menstrual cycle. If you and your partner want to understand her body more, start to learn the patterns of her fertility and try to conceive it’s well worth looking for an answer to the question ‘when do women ovulate?’.

The Monthly Cycle

Ovulation can vary from month to month and woman to woman, but a basic guide is that ovulation occurs 12-16 days before your period starts, with the end of the period marking the start of a fresh cycle.

If you’re trying to identify your cycle, and work out its duration, regularity and the length of its different component parts, it makes sense to start measuring from the beginning of your period: it’s easy to identify, and when it stops, you know to begin counting the start of a fresh cycle.

When you know when in a cycle your period generally falls, you can count back and start to identify a window in which you begin to ovulate each month. This is useful beyond trying to conceive: disruptions to your menstrual cycle are a visible indicator of other health issues, from stress right up to serious health problems, so knowing your cycle well enough to detect irregularities could give you advance warning of incoming issues.

Delays and Disruption

There are lots of things that can delay or disrupt ovulation, and it’s worth being aware of them. Stress is one of the biggest factors at play here: ovulation is triggered by hormones released by the hypothalamus – gonadotropins.

The hypothalamus is the region of the brain most affected by stress, and if stressed enough it may delay or cancel ovulation all together, so when you’re trying to conceive it’s well worth trying to minimise stress.

On top of stress, there are also medications that can interfere with this hormone communication and disrupt your regular ovulation cycle: steroids, thyroid medications and some blood pressure medicines can affect either the pituitary gland or the hypothalamus, as well as medications that work on the central nervous system.


If you’re trying to get pregnant, you should talk to your doctor as soon as possible to discuss how any medications you may be taking, or underlying health conditions can affect when women ovulate. On top of that, using OvuSense to track your fertility and ovulation let’s you know when the best time to conceive is, and helps you understand your menstrual cycle each month.
