The period is called menstruation, and you can get pregnant if you don’t use contraception right after your period.
Women are generally more likely to conceive during ovulation, which usually occurs about 14 days before the next menstrual period. The endometrium is in the proliferative phase just after menstruation, and the follicles have not matured, so pregnancy is usually not possible, but due to individual differences, if the menstrual cycle is unstable and there is an early ovulation, conception may occur.
If there is no plan to get pregnant, it is recommended to choose suitable and effective contraceptive measures, such as placing an intrauterine device, using short-acting contraceptive pills, and using condoms. Tubal sterilization can be performed if there is no requirement for childbearing. Safe period contraceptive methods are unreliable and are usually not recommended.
