Can you get pregnant if you have sex right after your period ends?

　　"Auntie" usually refers to menstruation. Generally speaking, if a woman has a long menstrual period but a relatively short cycle, she may get pregnant. However, typically right after the menstrual period ends, a woman is in a safe period. Additionally, if the male's sperm quality is poor, pregnancy may not occur. Detailed explanations are as follows:

　　If a woman has a long menstrual period but a relatively short cycle, she may be approaching or already in her ovulation period when her period ends, and having sex at this time could lead to pregnancy. Ovulation can be influenced by multiple factors such as environment, mood, and ovaries, and ovulation does not necessarily occur only during the expected ovulation period. Therefore, even shortly after the menstrual period ends, there is still a possibility of ovulation, which could lead to unintended pregnancy.

　　Some women are typically still in a safe period (i.e., non-ovulation period) shortly after their menstrual period ends, and the likelihood of pregnancy at this time is relatively low. Moreover, if the male's sperm quality is poor and the sperm survival time is short, having sex right after the menstrual period ends might mean the sperm cannot survive until the ovulation period, thus reducing the chance of pregnancy.

　　Therefore, if there is no plan for pregnancy, it is recommended to use contraception to prevent unintended pregnancy.
