I am 16, and have been on birth control for about 5 days now. I was put on it because of persistent and worsening PMS, cramps, and a very irregular cycle (last one lasted 3 weeks and was 2 weeks early). Ever since I began taking it, I have been experiencing nausea like I've never had before. Not a second goes by where I am not feeling like puking. I constantly have to eat something sugary in order to not vomit. Along with the nausea, I have been having episodes of shaking/twitching that begins in my hands and eventually effects my whole body. The shaking/twitches are not minor shivers like what you get when your cold, but they're not quite as severe as seen in a seizure. I have an immense amount of pressure in my lower stomach that will spontaneously turn into a sharp pain for a few moments before going back to the normal dull pain. I have no control as to how any of this will happen or how to stop it. My gynecologist told me to take it at night after I've eaten and I do so. I don't know why this nausea is so bad, or what's going on. I take microgestin FE 1/20 every night with my vitamin D supplements, vitamin C supplements, zertec, probiotics, and teen multivitamin. In the morning I take vyvanse, pristique, and zertec all after eating. Will this continue on, and if so- for how long? I have to go back to school on this following Monday, but I don't think I'll be physically able to function. Is this normal? Is there anything I can do?
