The first thing you need to clarify is the type of contraceptive pill you take, generally short-acting or long-acting contraceptive pills do not need to worry about, while emergency contraceptive pills need to pay attention to, may cause some adverse reactions. 1, short-acting contraceptive pills: generally 28 days as a complete cycle to take, so within 10 days to take two times the pill is normal, follow the doctor’s instructions can be taken to avoid missing; 2, long-acting contraceptive pills: on the day of menstruation, after lunch on the fifth day to take a second pill, also can be taken on the fifth day and the tenth day each. The long-acting contraceptive pill: take the pill once after lunch on the fifth day from the day of menstruation, and take the pill for the second time at an interval of 20 days, or take 1 tablet on the fifth day of menstruation and 1 tablet on the tenth day of menstruation, so the long-acting contraceptive pill can be taken twice within 10 days. If you take emergency contraceptive pills for 2 times within 10 days, it may lead to menstrual disorder, vaginal bleeding, breast pain and other symptoms, and affect female endocrine system. Therefore, women need to note that the emergency contraceptive pill is only a remedial measure and is not recommended for routine use, up to 1 time per month and up to 3 times a year. It is recommended to use condoms for contraception on a daily basis, which is effective.
