Is it harmful to the body to take too many birth control pills?

Patient's question:

Symptom Description: Currently, there are no reactions, but I am afraid of getting sick in the future. Treatment history and effectiveness: No treatment has been given, just want to know the result. What kind of help do you want: I want a good result

Doctor's answer:

First, you need to figure out what type of birth control pill you are taking.
Long-acting birth control pills. These contain synthetic progestins and long-acting estrogens. After entering the body, the medication is stored in fat tissue and released slowly over time, inhibiting ovulation and providing long-term contraception. They are suitable for women who cannot have an intrauterine device (IUD) inserted or are unwilling to use other contraception methods. The main type is combined long-acting levonorgestrel tablets. Generally, one tablet is taken on the fifth day of menstruation, and another is taken after 20 days. Their effectiveness is lower than that of short-acting birth control pills. Some women may experience increased vaginal discharge, menstrual irregularities, pregnancy-like symptoms, and occasional bleeding that is difficult to control. In rare cases, allergic reactions may also occur.
Short-acting birth control pills. The main components are progestins and estrogens. They work by inhibiting ovulation, blocking the normal growth of the uterine lining, altering the consistency of cervical mucus, and changing the normal movement of fallopian tubes. They are suitable for women without underlying conditions or diabetes.
