I am experiencing white vaginal discharge, itching, and swelling inside my vagina. The vaginal opening also seems to have become smaller. My period was due three days ago, but it still hasn't started. I was sexually active 10 days ago, and I am worried that these symptoms might be signs of pregnancy. * Could these symptoms indicate pregnancy, or could they be caused by a vaginal infection? * If it is an infection, can it be treated completely? * How long does treatment usually take, and will the infection affect when my period arrives? * What treatment or medication might be needed? * Approximately how much would a doctor's consultation, necessary tests, and medicines cost
