If said 15 year old girl and 17 year old boy have sexual intercourse then yes. If this sex was unprotected then there is obviously more chance pregnancy may occur. If you used contraception you will probably be safe, but the only 100% effective form of contraception is abstenence (not having sex).
Age doesn't really matter when you having sex, in fact the younger you are the easier it is to get pregnant, as your eggs and his sperm are still very young so very mobile. Obviously as long as you have started your periods. Depending on the time in your cycle you had sex alters the chances. Around the middle of your cycke you are your most fertile, so most likely to get pregnant ( day 14ish).
