Theres always a chance of pregnancy if you're having sex. That's why if you're not planning on getting pregnant you should always wear a condom and or other forms of birth control.

Depending on your cycle . If you have a 28 day cycle then its not likely. You ovulate on or around day 14 of your cycle with day 1 being the 1st day of your period. Sperm can survive a max of 5 days in the uterus but on average it is 2 days. If you have a shorter cycle it is more possible but still not that likely.....How long exactly are your cycles?
