I am extremely scared. I am 19 years old and in my second year in college and i think i might be pregnant. I am on birth control and i missed the fourth day of the first week of a pack...i took it the next day when i remembered. That next weekend i had unprotected sex with my boyfriend but he did not go in me. I know there is always a chance even though they do not go inside of you but thats why i feel more comfortable on the pill. But since i missed that one day the previous week i am extremely nervous that i could be pregnant. What is the likely hood of me being pregnant...any thoughts?
