Why am I bleeding but not getting my period?

Possible Reasons for Bleeding Between Periods

There are several common factors that may cause bleeding outside of your regular menstrual cycle. These include the use of hormonal contraception, like the contraceptive pill. Additionally, the presence of small growths in or around the uterus, such as polyps or fibroids, can lead to unexpected bleeding. Furthermore, sexually transmitted infections (STIs), including chlamydia, may also contribute to this issue.
