Had sex with condom then a couple hours later started period what are the chances of being pregnant?

Not likely pregnant: Young women that have sexual intercourse with a partner using a condom and then start their period at the expected time in their menstrual cycle are not likely pregnant. It is best for you to use condoms to prevent pregnancy and some sexually transmitted infections but also to use a second method of birth control like pills, , Nuvaring, Depoprovera injections, or contraceptive implant in addition

TruePeriod = NotPreg: A girl cannot get her normal regular period and be pregnant at the same time. However, she can get pregnant a week or two after her normal period. If she has some spotting or light bleeding that doesn't look like her normal regular period, she can check a urine pregnancy test about 3 weeks after sex (3 weeks after when conception might have happened) to see if she is pregnant.
