Yes, you can get pregnant the first time you have sex. Any time semen is near the vagina, there is a risk of pregnancy. Use a condom every time you have sex (anal, oral, vaginal, hand) to reduce the risk of pregnancy, STIs and HIV. Using two methods of protection, called dual method use (using a male or internal condom along with another method of birth control like the pill, patch, ring or IUD) provides the best protection from pregnancy, STIs and HIV.
