I was ovulating the beginning of the week. I was very emotional this week also. Thursday I had sex, a little rough, then Friday I have a brown discharge with a slight itch. Today there is more, it's pink/brown, smells like wet dandruff, and I am having cramps the last few hours. Sex was unprotected and I am not on birth control. Is my period starting early? I had cervical bleed earlier this year. Paps have been normal besides one abnormal one 4 years ago. Should I go to the doctor?
