From the beginning shall we? My last period started September 27th and ended October 2nd. I had unprotected sex October 7th. Then October 17th I'm spotting. It lasted a few days. Dark for one day then the next it was a light pink and brown. Then I feel nauseous consistently. On and off all day. I'm exhausted. I go lay down for bed at 7 and still am tired in the morning. My period is late. I had a white discharge in my panties yesterday. I just dont know what to think. Am i?
