Ok so i had my period on 6/6/08-6/12/08(6 days)so i went to the doctor for a check up and she said that i had a soft low cervix and an enlarged uterus so she did a pregnancy test and it was neg. so she did a blood test and i guess it was neg. so my period was due yesterday but no period and no symptoms that my period is comming so i dont really know whats going on any ideas? Doctor was no help!!
