Is ectopic pregnancy possible with a visible gest-sac? Had u/s at what I believed to b 7wks. U/s only showed 5.3wk empty sac. Dr said poss ectopic.

Not likely. Yes, it's possible but rare. The trick is if your doctor was certain he/she saw a gs or some other intrauterine fluid collection. With a sure gs, risk of also having ectopic is exceedingly low.
