Ok in April on like the 12th I went to get the shot well I hadnt been on protection before then besides condoms well the day I went to get the shot I was suppose to get my period they didnt do a prenancy test and gave me the shot anyway. Well the other night over the weekend I fell backwards in a chair when I got up it felt like something was down there so I went to the bathroom and there was a bloody mucusy snot looking clot like thing there. It was about a little bigger then a fifty cent piece. SOMEONE HELP ME?? WHAT HAPPENED??
