I recently made a huge mistake and had unprotected sex. He claimed he did not ejaculate inside but since I'm a worrier I took plan b one step around twelve hours later. I was on the last day of my period when we had sex. It's been 5 days and I'm still experiencing symptoms such as headaches, blood/Brown discharge. Today (the 5th day since I took the pill) is one of the worst. Sometimes when I first get my period I get sick to my stomach and today I felt like that. Also today is the only day I've seen the brown or blood discharge when I wipe. Is this normal?? How long do these last? Should I seek medical attention? I can't let anyone know about this so I'm extra scared. Please let me know your thoughts.
