Which method should be chosen for an abortion to cause less harm to the body?

Patient's question:

Detailed medical condition and consultation purpose:
I am living together with my boyfriend unmarried, and I haven't had my period this month. After checking at the hospital, it was confirmed that I am pregnant. Due to various circumstances, I cannot keep this baby. Please advise which method of abortion would be less harmful to my body. Will the big hospital perform an abortion for me? Can I do it without parental consent? (I don't want my family to know) What documents are required? How much will the surgery cost approximately?
Will I bleed for half a month after the abortion?
I'm so scared!! Please help me!

Hello

During induced abortion, many complications may occur, the most life-threatening being the heart-brain syndrome. Other complications include bleeding, injury, cervical adhesion, pelvic inflammatory disease, etc. Repeated multiple induced abortions are the most harmful. Firstly, the risk of uterine injury increases, and the damage to the endometrium caused by induced abortion directly affects future fertility. A clear change is that menstrual volume decreases after an induced abortion. The amount of menstrual flow is a direct reflection of the condition of the endometrium, and a reduced volume indicates endometrial damage. Additionally, induced abortion damages the basal layer of the endometrium, making it easy to experience implantation during future pregnancies, where the fertilized egg embeds itself like roots growing downward. Subsequent induced abortions become more difficult to clean, requiring a second. Furthermore, complications such as inflammation may lead to infertility and ectopic pregnancy.
After an induced abortion, women should rest for 2 weeks, as it creates trauma inside the uterus. However, many women do not rest after the procedure and return to work or school the next day, which causes significant harm to their bodies. In the 1980s, China conducted a large-scale survey, which found that women who rested for 2 weeks and took medication diligently had fewer postoperative bleeding times, bleeding volumes, and chronic pelvic inflammatory disease compared to those who did not rest.
