I'm taking contraceptive pills for almost 6 mos now and antibiotics for my newly pulled tooth for almost 4days now .and i have sex last 6 days ago i had a rough wild sex and after that i felt pain in my vagina , i ignore it because i thought it's only abrasions but after two days i felt more pain and theres an excessive yellow discharged i checked it and i saw 1 long red flesh. and I'm so scared. Sorry for my english. My yellow discharged almost like a pus but didn't smell anything or not even itchy . Please help .
