There is no such thing as the safest contraceptive pill, and no contraceptive pill can be 100% effective, because there is a possibility that the contraceptive pill will fail and the accidental situation will lead to pregnancy, even if the birth control ring is placed in the woman’s uterus, there are very few women who get pregnant with the ring, and the incidence of this situation is very low. The choice of contraceptive medication should be based on your specific situation. If you have regular sex with menstrual disorders, you can use short-term contraceptive medication under the guidance of a doctor to regulate your menstruation while using contraception. Long-acting contraceptives can also be used, which are more convenient to use, but because they contain larger doses of estrogen and progestin, which may have health effects, they are now used sparingly.
