I had unprotected sex on december 9, 2013. Exactly two weeks later i had a brownish discharge and myperiod was very dark and lasted 3 days. I usually go heavy for 5 days with of course the color beng blood red. Today is January 12, 2014. I have been very moody, emotional, had an increase in fatigue, and my stomach feels weird. Can you please get back to me as soon as possible? Thank you.
