My fiance tried aborting on Cytotec last week and it didn t work out for her ( she was in the 5th week of pregnancy ) . She had an abortion by vacuum on Saturday 8th of October afternoon, she did put out some blood on Saturday evening and Sunday morning. The problem is that she is suffering from a sever back ache , can you please inform me if this is normal after such operation? The bleeding has stopped almost completely . When should her menstrual period get back ? the last period she had was on the 25th of august.
