Is it okay to have sex with your wife from the inside?

Patient's question:

No

Doctor's answer:

Hello, as you said, you want to use the safe period method for contraception. The so-called safe period refers to the three days before the onset of menstruation and the three days before menstruation ends. These days are absolutely safe. If you have sex without taking any contraceptive measures during these days, the chance of pregnancy will also be relatively small. The premise of the safe period method is that the menstrual cycle is relatively regular, allowing you to predict the next onset of menstruation. Otherwise, pregnancy may still occur.
