Thank you.
Quit having sex until you see a doctor, but you need to wait for your period to end.
Not having sex isn't a problem as that won't happen for like a month. I only noticed the last time I had sex that the pain was still there (which originally I thought was cased by a razor cut and didn't think much of it so I quit shaving, but it still hurts, so yeah, I'm getting it checked out).
As for right now, do some research about it online.
