If you have unprotected sex and have missed your period, you are probably pregnant. Some women feel some cramping when the egg implants into the uterus. If you think you are pregnant, take a home test or go see a doctor.

You would not menstruate at all if you were pregnant, and in theory you would not have been fertile at the point you had sex, so you'd not fall pregnant. However unless you use fertility awareness method you can't know when you are fertile or not, so pregnancy is a possibility.
It is entirely possible that pregnancy could occur if she is fertile. This is no different whether the woman is a virgin or not.
It is possible to get pregnant at any time. 9 days before your period, you are very fertile. Make sure you use protection unless you are trying to get pregnant
from the time a girl/woman starts her first menstrual she has the ability to become pregnant. but, you are only fertile between 12-24hours. then the ovum will being to break down. your only fertile those hours every25-35 days. that's why people arent pregnant every time they have intercourse.
