Well, honestly to know your chances you'd have to say when your last normal period was. You'll usually ovulate about 14 days before your next period, if you have a normal 28 day cycle. If its longer, than it can increase to 16-18 days before your next cycle. If the two of you used this pull out method during your ovulation time, then you may have a chance. It usually takes alittle more than 2 weeks for you to notice symptoms, but some women notice alot sooner than others. It depends on your body. Anytime you have sex without a condom, you have the risk of pregnancy. Just because guys have pre cum and they don't always feel some of the little stuff coming out during their excitement. I am in this boat right now and sure of pregnancy. Good Luck, on whatever your wanting.
