Suggest Treatment For Discomfort In Vagina After Intercourse

I had sex for the first time 4 days back. I bled a little. We used edible olive oil as lube. I am feeling discomfort in my vagina when I sit. There is no itching or burning while peeing. Is this normal? Or I am starting to have an infection? Should I use the clitromazole vaginal gel? Or I should visit a doctor? Really worried . please help.
