What are the effects of taking emergency contraception twice within a month on the body?

Patient's question:

No

Doctor's answer:

Do not take it a second time within a month, as it can harm your health and may render the medication ineffective. Within a year, it is best to take it no more than three times. This medication poses significant risks to women, including menstrual disorders, prolonged bleeding, nausea, vomiting, headaches, dizziness, fatigue, breast swelling, bleeding, and even potential infertility in the future. These are some of the common side effects.
