It’s certainly possible you’re getting your period early; however, bleeding can also be a sign of something serious like an infection or injury, so, yes, you should definitely see your gynecologist or go to your nearest women’s clinic. If it were me, I’d want to know whether I have a condition that needs to be treated. You may simply have an irritation, or it might be something more serious. But no one can tell you what’s wrong without conducting a physical exam. Why are you frightened of seeing a doctor? Now that you’re being sexual with another person, you need to take responsibility for taking care of your sexual health. Good luck to you. Dr. J
