I saw the dr yesterday they did a ultrasound and saw the sac where the baby will grow I’m just 4 weeks 3 days so nothing else was detected.  I go back in 2 weeks for another ultrasound to see if there is something growing in the sac and if there is a heart beat.  She said thier was no reason to take dex if no cells are present yet.  Which makes since, she said she usually starts dex treatment at 6 weeks.
