What causes ovulation spotting?
Some women experience light spotting around the time of ovulation — typically mid-cycle. This is thought to be caused by the rapid hormonal changes that occur as oestrogen peaks and then dips just before ovulation, causing a small amount of the uterine lining to shed.
It's usually very light — a few spots of pink or brown discharge — and lasts a day or less. It's generally harmless and is actually a sign that you're ovulating, which can be useful when tracking your fertile window.
When is spotting not normal?
While ovulation spotting is usually nothing to worry about, other types of bleeding between periods should be investigated. This includes bleeding after sex, heavy spotting, or bleeding that happens at irregular times in your cycle.
Spotting can also be caused by hormonal contraception, cervical changes, polyps, infections, or — less commonly — more serious conditions. If you're concerned, or if the pattern of bleeding has changed, see your GP.
Getting it checked
If you're experiencing spotting and aren't sure whether it's related to ovulation, your GP can help. They may arrange a pelvic exam, Pap test if due, ultrasound, or blood tests to check your hormones and rule out other causes.
Tracking when the spotting occurs in relation to your cycle can help your GP determine the cause. If it's consistently mid-cycle and very light, it's likely ovulation-related. But always get new or unusual bleeding assessed.
