my last lmp was on sept 5 2009 it started with a brown spots. then on october 28 2009 i had a pregnancy and it turned out to be positive. on the 29th of october i went to my ob=gyne to have a prenatal. my ob-gyne suggested i should have an ultrasound becuase i had a previous prenancy which turn out to be anovulatory. when the ultrasound was done my ob-gyne only see a gestational sac. i hve a long cycle. im really worried if the gestational sac is viable to becone an embryo. im having breast tenderness and numbness.when we counted it she estimated it to be 3-4weeks old. im worried. any assurance from anybody there?
