So recently my boyfriend and i were dry humping. both fully clothed. i've been anxious because three days later i started feeling sick. i feel like throwing up. he had a bit of semen on his underwear but it didn't go past. is it possible i'm pregnant?

You sound like you are coming down with an illness, but pregnancy is not the cause. Three days is not enough time to have any symptoms of pregnancy after exposure. The cited fully clothed activities also don't create a pregnancy.

While you are not at risk of pregnancy from this episode, your behavior is putting you at risk of pregnancy and STDS.
