What are the dangers of long-term use of long-acting birth control pills?

Patient's question:

I noticed that I always take birth control pills before having sex. Sometimes after finishing work, for safety, I take many emergency birth control pills because I feel very upset about getting pregnant. I haven't been ready to have a child. What are the dangers of long-term use of long-acting birth control pills?

Doctor's answer:

Hello, any medication has side effects. Contraceptives may cause endocrine disorders, menstrual irregularities, amenorrhea, infertility, or gastrointestinal discomfort, headaches, weight gain, nervousness, low mood, skin hyperpigmentation, and acne, among other issues. Considering the side effects of contraceptives and their potential harm to the body, you can choose alternative methods such as condoms or intrauterine devices based on your personal circumstances to breastfeed. The above information can serve as a reference.
