Hi i am 21 years, My last day of my first period was on 3rd nov, finished on the 7th nov i had unprotected sex on the 13th of november 2010 he ejaculated inside me without me realising until after he had done so. i panicked ran to the loo and went to lay back down, worried what would happen next. on the 15th i experienced alot of mucus discharge for a week im geussing it was ovulation week, but since the 15th i have been having discharge everyday, tommorow i will be 6 days late with my period, the day before my due period i took a pregnancy test and it come out negative.. today i had light red blood along with the clear thick mucus discharge.. could this mean my periods coming, or is this spotting ? during this time i have had sore breast / nipples, headaches that i rarely get and light cramping. never experienced any other time.. is this just one of those things or is something going on here ? please help me understand
