My best friend and I were fooling around and ended up having sex about a week ago (*Seven days to be exact). The next morning, it seemed that I had some vaginal discomfort and the few days that followed some yellowish vaginal discharge. I also began to feel very dizzy, and nauseous, but I do not have to urge to throw up. My body feels drained and fatigued and i have been having awful headaches and lower abdomen pain. I did some research and I am very worried on the information that I found! I would like to know what other think and if anyone could tell me something to ease my mind on the thought of actually being pregnant.
