Patient's question:
I am currently 18 years old. Because I had sexual intercourse with my boyfriend, my period hasn't come now. I want to know if this is because I might be pregnant. Additional question: I didn't use a condom with my boyfriend, but he practiced withdrawal.Doctor's answer:
External ejaculation is relatively safe, but it is not 100% effective. Sometimes, if not controlled properly, a small amount of semen may enter the vagina, leading to the possibility of contraceptive failure. During sexual intercourse, when both partners are at the peak of excitement, a small amount of semen may overflow along with the contraction of the vas deferens and enter the vagina. Although the amount of semen is small, it contains the highest number of sperm, making pregnancy possible. It is recommended that you use a pregnancy test kit or undergo an ultrasound, blood HCG tests, or other relevant examinations after a week of delayed menstruation to confirm whether you are pregnant.
