I an unmarried 22 year christian woman who had sex mistakingly and did not use protection. My boyfriend did not ejaculate inside me. I was on my period or just finishing it while this went on. My period ended on January 6 or 7. Then this past Friday on the 19th I experienced a very light pink discharge and experienced it on sat as well. Then on Sunday I began what seems like a period, but it is not at all like a normal period. I am not experiencing any of my normal period symtoms: i.e. cramps, tender breasts, emotional, etc. I found out about implantaion bleeding and am very afraid I am pregnant. Are my symptoms a good indication of what could be a pregnancy?
