Hi! I am new to this site I've never really been on a forum. I was wondering what would cause my period to be late. I had my tubes tied 6 yrs. ago and have taken several preg tests all negative. I had bloodwork done today will find out Monday if there is anything. I am now feeling sad that I am not pregnant. I was wondering what might be the cause. I haven't been stressed out or anything. If anyone could help I would appreciate. Thanks Jenn
