hi, i am a 17 year old girl and i recently was doing ''things'' with a guy. some semen got on my underwear, but not near the opening of the vagina, some got where my pubic hair sits but im scared that some MAY have gotten onto other places on me, but keep in mind, my underwear was on. (ps we did NOT have sex) i am now freaking out that i may be pregnant, and i am overlooking everything. to me it seems that my stomach is getting bigger, i gained 3 pounds, and etc. could i possibly be pregnant? im really scared, and i have no idea what to do, and i am not at ALL interested in babies right now...
