I recently tried to had sex with a tampon in, but felt something weird (which was the tampon)and didnt know i had it in so we stopped about 2-3 minutes into it. The next morning i woke up and realized that i had it in and immediately took it out. Its been about 4 days now and I recently tried having sex again and i feel like it doesnt feel the same- it feel like it might be inflammed. I am scared i might have hurt myself. Is there anything OTC that i can take to help with it?
