You had penetrative sex with your girlfriend 12 to 16 dates before her next period. You are sure that no semen entered but pre-cum did enter. In truth, pre-cum do have some sperm cells, but those cells are not enough to enter the vagina, meet with the ovum and fertilize it. Still, there are chances for pregnancy. Please consult a gynecologist for pregnancy test. If you require more of my help in this aspect, please use this URL. Make sure that you include every minute detail possible.
