hey i know its scary to post something and have no one answer so im going to give you my opinion on this matter. i dont think that your symptoms are due to the birth control. however, it does sound like your body is fighting something. you could just have a cold/flu. if i were you, i woudl stop taking the birth control, wait until you get better and then try it again. if the same thing happens then you know it's the birth control. im having problems with my vision right now and the only thing i can think that is causing it is the bc im on. im going to stop taking it and give it a few months to clear up. with your fevers though, if you stop taking the bc now, in a couple days/one week if it is the bc causing it, i would think you would feel a whole lot better. the doctor that gave you the antibiotic, what did he/she think it was? ive never heard bc doing this but i do know that it can affect people differently. try to stay calm, i know i would be freaking out too but if you remain calm you'll feel better. stress will only make you more anxious. im sorry this is happening to you. doctors perscribe us these pills to "fix" our problems but they arent the ones who have to go through the side effects. it can be really scary when you feel like your body is out of control and you dont know what is happening. i hope you feel better soon.
