During the sex

YES its called the pull out method and it does NOT work because semen can be present in pre-cum (released every now and then nefore you ejaculate) so she can very well get pregnant to find out if shes pregnant tell her to take a pregnancy test 2-3 weeks after you had sex (any sooner and the results won’t be accurate) in the morning with your first pee is the best time and take it when your period is due alternatively, see a doctor for a blood test this will both let you find out quicker and give you more accurate results and you and her BOTH need to LEARN about sex before you go off having it learn about as well as a male and female reproductive system birth control, contraception, pregnancy and sti/stds don’t have sex until you know the consequences involved with it because the main reason why kids and teens get pregnant and get stds is because of a lack of sex education
