I had sex two weeks ago and i was on y ovulation days, it was unprotected sex. After a week i got brown spotting lasted for 5 days and my period is due next week. I was wondering about that brown spotting did any one experience that before she found out she was pregnant? Also today i am tired and sleepy and i am having needles pokes in my right breast with sharp pain in my down left side of my ovary and back. I am having little fatigue which is off and on
