for the last three days i have been very sick... extremely sore swollen throat, clogged ears, fever, vomiting, pain in the right ear, right side of the throat is worse. i started out on a z pack for 24hrs and that did not work, switched to "amoxicillin and clavulanate potassium tablets" yesterday morning. they did a strep test and it was negative, also did a mono test that came back negative. they said if i dont feel better in several days to get re-tested for mono.. but my question is between the vomiting and the sickness and all the different meds (including bayer asprine) can this cause me to have a periods? i've been on depo for almost a year now and after about the first two injections my periods had stopped completley. i know im not pregnent so that cant be it. all i can figure is its from being sick and the meds... am i right?
