Patient's question:
Because I had unprotected sex with my boyfriend again recently and took levonorgestrel tablets afterward, but now my period is delayed and has been intermittent, a bit irregular, so I'm very worried. I want to ask what to do about menstrual irregularity after taking levonorgestrel tablets?Doctor's answer:
Because the main component of levonorgestrel tablets is a high dose of progesterone, after oral administration, it can affect the existing endocrine function of the ovaries, leading to endocrine dysfunction and resulting in menstrual disorders. The recurrence of this phenomenon is due to the early shedding of the endometrium caused by progesterone, resulting in abnormal menstruation. In this case, it generally can return to normal on its own without special intervention. However, frequent oral use of emergency contraception can lead to severe menstrual disorders.
