so I had sex on November 9th, 2014 (more than once) immediately after I started feeling lower abdominal pains, and there was a lot of pressure/pain when I went to pee (not burning or itching, just a lot of pressure) and I took Plan B on November 10th, 2014 (but it was hours after the 24 hour mark). Initially, I didn't have any symptoms, but about 5-6 hours later I started feeling really nauseous, and really exhausted, I felt really woozy, and I had insane cramps! (nothing compared to menstrual cramps) and that continued.. then on November 12th, 2014 I started feeling super bloated, and I couldn't eat anything at all. I could barely walk, let alone stand. I went home, and Had really bad diarrhea. I still decided to tough it out, until later that night, through Thursday, November 13th, which is when I kept vomiting non stop. That's when I decided to go to the emergency room. (I read that vomiting after the 48 hour mark was not normal, and diarrhea was also not common, so I should contact a doctor). When I went to the emergency room, the put me on an IV because my body was dehydrated after all the vomiting, and they took blood (which kept clotting). they said it MIGHT be a bad reaction to the plan B or just a virus (im sure it's not a virus). They also told me to make an appointment with an OBGYN and to follow up with them in a week or so after taking a pregnancy test (because right now it's too soon to tell) They prescribed me Zofran (4mg) and ibuprofen (600mg) which both do not work for me. I'm still nauseous and in pain. the only thing the Zofran does is keep me from vomiting. I have no appetite, (except for saltines and Gatorade) everytime I eat, I get sicker, and I have a sensitivity to smells as well (for ex, my mom had coffee, and I started throwing up) I know this is a lot, but I wanted to be as detail oriented as possible. Does anyone know what might be going on with me ?
