How harmful is it for a 43-year-old to take 2 emergency contraceptive pills in 48 hours?

The main danger of taking two emergency contraceptive pills in 48 hours in a 43-year-old woman is the risk of contraceptive failure, which may lead to menstrual disorders.
Emergency contraceptive pills are a remedy for contraceptive failure, with relatively high drug dosages and significant adverse effects.
1. Contraceptive failure. Emergency contraceptive pills are less than 100% effective, and contraceptive failure may occur even when emergency contraceptive pills are taken correctly. If there is a delay in menstruation after taking the pill, you need to test your urine with a pregnancy test or a pregnancy test first, because there is a possibility of contraceptive failure.
2. Menstrual disorders. 43-year-old women with diminished ovarian function are prone to menstrual disorders, and taking two emergency contraceptive pills within a short period of time may lead to menstrual disorders, such as early menstruation or delayed menstruation, or even abnormal bleeding.
Women who have no desire to have children are advised to use strict contraception to avoid unwanted pregnancy.
