Patient's question:
[Condition Description: First ML, boyfriend used withdrawal method, two days later had ML again, still used withdrawal method, will I still get pregnant? My menstrual cycle is often irregular, sometimes early, sometimes in the middle, and sometimes at the end of the month. How can I determine the safe and unsafe periods? Medical history and effectiveness: No treatment has been received. What help do you need: I don't want to doubt.Doctor's answer:
The withdrawal method, also known as the coitus interruptus method, is a form of contraception based on a physiological phenomenon in males. The male orgasm is divided into two stages: the first stage, where semen is concentrated at the base of the penis, is called the "inevitable ejaculation" stage. After a few seconds, it reaches the second stage, the "ejaculation" stage, where semen is expelled through the urethra. When using the withdrawal method, the man withdraws his penis from the vagina during the inevitable ejaculation stage, and the ejaculation occurs outside the woman's body.The withdrawal method does not prevent pregnancy, as pregnancy requires the combination of sperm and egg. However, it cannot be entirely ruled out that sperm may enter the vagina. If there is uncertainty about whether pregnancy may occur, a blood hCG test can be taken about 10 days after intercourse.
