You can have a baby the same month you get pregnant after hysteroscopy. In general, it is recommended to have a menstrual period before having a baby after hysteroscopic lavage because methylene blue is used for hysteroscopic lavage, which has teratogenic effect on the fetus, but the effect is rapid and can be excreted through urine without metabolism. most of the methylene can be excreted through urine within 6 days, and a small amount can be excreted through bile and feces. Therefore, if you have a menstrual period after the operation, there is no effect on the baby, but if you get pregnant in the same month after the hysteroscopy, you can also keep the baby.
