HELP!! yeast infection

jane

what do i do if i have a yeast infection? i am 100% sure i have a yeast infection. i have chunky & white discharge, it smells like yeast, & after i had sex it burned soooo bad & it hurts. what is the best medication that doesn’t cause pain or could kill me from an allergic reaction? i need something that i can get now, & my gynecologist isn’t available any time soon. please tell me what worked for u & what side effects i should expect from it.
