I took plan b two weeks ago today. The first few day I was extremely sick, throwing up, not hungry, headache, weak, abdominal pains, and diarrhea. About 4 days after I was spotting brown and red for a couple days. Then I was really irritated in my vaginal area with some white secretion (possible yeast). Now for the past couple days I've been extremely itchy all around my face but mostly around mouth, nose, eyes, and top of my forehead. I still have an occasional abdominal pain even in my side. My eyes are red, itchy, and feel tired throughout the day. My throat is sore with a single white spot way in the back. Could this be herpes? I'm going to get an std test later today but if symptoms aren't common they usually brush off the possibility of it being related to the pill. Could I be having an allergic reaction? Or worse both herpes and allergic reaction?
