I had sex with my boyfriend on April 7 and he may have came early. I ended up taking plan b on that Friday the 10. And now as of yesterday Thursday the 16 I noticed spotting and than kinda got heavier but not enough for me to think is was my period. Now today when I get up its almost like my period except lighter than normal My last period was march 30 to april 4, this normal or should I be worried??? Please help
