Spotting during ovulation is typically caused by hormonal changes in the body. Around ovulation, estrogen levels rise leading up to the release of an egg, and then there is a small dip in estrogen levels right after ovulation, accompanied by a rise in progesterone. This hormonal shift can cause a small amount of the uterine lining to shed, resulting in light spotting or bleeding, often pink or brown in color. This is relatively rare and occurs in fewer than 5% of women. The spotting is usually light, brief, and not a cause for concern. However, if it is accompanied by pain, lasts longer, or is heavy, it may warrant medical attention. Spotting can also occur due to other reasons like hormonal birth control use or underlying conditions, so consulting a doctor is advised if there are worries.
