When are you most likly to get a girl pregnant?

When she's ovulating: If you are trying to avoid pregnancy... Use a condom.... That way you can stay in control. It is the responsible thing to do, and will offer protection from sexually transmitted disease. If you are trying to get pregnant, then discuss it with your partner. She may have a good idea of her "fertile time" on the basis of her vaginal/cervical secretions and mood.

Depends: Pregnancy has been documented after unprotected sex on any day of a woman's cycle,including during menses. In theory. women are most "fertile" in the days surrounding egg release (usually mid=cycle).Sperm need to encounter the egg in the Fallopian tube,fertilize it, and the material implant in the womb in that order.No one knows for sure when egg release occurs.
