Well today i had an early u/s and the tech couldn't see anything so she tried a vaginal u/s and you can see a sac but nothing in it.My lmp was Nov 11th.So i should be about 4weeks and a couple of days.What can be seen this early on a u/s?I'm freaking out because my Dr. mentioned miscarriage and now she wants to run a 48 hr hcg blood test and follow up with a u/s in 2 weeks.I'm stressed out [2] now.i also posted this on the Aug ec to see what othewr preggo mom's think.What do you ladies think?Any advice would be appreciated or any insight.Thanks!
