If you want to get pregnant and have a baby after taking the Yutin contraceptive pill, you should take at least 3 months, and preferably 6 months, between pregnancies before having a baby. Yutin is a kind of emergency contraceptive pill, which contains a relatively high activity, large dose of progesterone. These exogenous progestins will affect the normal endocrine function of the ovaries, and will also affect the state of the endometrium, which may result in irregular vaginal bleeding, and ovarian ovulation may also be inhibited. It takes about 3 months for these effects to return to normal. If you prepare for pregnancy before the endocrine function of the ovaries has fully recovered, you may have a lower chance of conception due to abnormal ovulation. Or after pregnancy, it is easy to have a miscarriage due to insufficient progesterone levels because of poor ovarian function. Therefore, after taking emergency contraceptive pills, it is usually necessary to take at least 3 months before considering pregnancy.
