    If you’re experiencing ovulation bleeding or any spotting or bleeding between your periods, you might be wondering what’s going on. A Flo expert explains why it happens and when to see a doctor.

    Any bleeding between your periods can come as a surprise, especially if it hasn’t happened before. The truth is that spotting can be caused by lots of things — including fibroids or a sexually transmitted infection (STI) — which is why it’s a good idea to get checked out by your doctor. But did you know that ovulation can also be a trigger?

    Ovulation is the point in your cycle when one of your ovaries releases an egg in the hope it will be fertilized by a sperm and you will become pregnant. This happens around halfway through your cycle. So this means that if you have an average 28-day cycle, it will probably happen around day 14.

    About 5% of people with periods experience bleeding around ovulation,” explains Flo expert Dr. Allison Rodgers, reproductive endocrinologist, obstetrician, and gynecologist, Fertility Centers of Illinois, US. So if you do experience ovulation bleeding, what exactly is going on? We’ve got the lowdown here.

    Key takeaways

    • Ovulation bleeding is caused by hormonal changes
    • This kind of bleeding is much lighter than a period and only lasts for a day or two.
    • There are lots of other reasons why you might be experiencing bleeding between your periods, from pregnancy to fibroids, so it’s always worth speaking to your doctor to figure out what’s going on.
