I am 12 weeks, close to 13. Saturday night I started getting a head ache and running a low fever (99). Sunday I was feeling awful, almost like the flu. Chills all over. Low fever still 99. Sore throat like no other, not able to eat much. Just feeling sick. I called the dr. because I was worried that I might be taking too much medicine. The only thing they are letting me take is tylenol products. I kept taking tylenol extra strength to make my head and body stop aching and to keep the fever down. She said it was okay to keep taking it, just follow the recommendations on the bottle so that I wouldn't consume too much. All night last night I was freezing with three blankets on and chilling and didn't sleep very good. This morning I haven't been feeling achey but I just puked up everything in my stomache. What in the world is going on? Anyone else experience this? I have had the flu shot.
