Welcome to HCM.
You have missed period of 2 months and last scan shows that early intrauterine gestational sac
without fetal node and about to 5-6 wks pregnancy
At this stage USG scan only rule out Gestational Sac and nothing more about fetal profile. So you have to wait an other 2-4 wks to get detailed feto-placental profile.
In this time, you take Folic acid
and vitamin supplements for better well being of fetus.
So don't be much tensed,take healthy diet, adequate sleep and avoid heavy work & stress
