had unprotected sex a couple of days before i got my period. during my period i started experiencing pain around my vaginal area. when i touched the area, when i contracted, when i sneezed, when i sat a certain way it hurt. I thought it was because i put in my tampon wrong but my period is gone and im experiencing slight blood. also brownish discharge..and it still hurts...I experienced a bad headache when i dont usually get headaches and i have been feeling tired, and lightheaded. I made a appointment for the doctor but im scared and have many questions now.any answers?
