I'm a 17 year old girl and 3 and a half weeks ago I had unprotected sex, but I'm on the pill and he pulled out. But the past week I've been feeling nauseous and even vomited once at night, I also have a stuffy nose. I read online that these are symptoms of pregnancy, but I'm not sure if I'm just jumping to conclusions or I'm actually pregnant, I also have the creamy white vaginal discharge
