Hi, Thanks for using HCM.
Normally by the end of 6 weeks cardiac activity should be seen by transvaginal scan. absence of embryonic mass or cardiac activity need to be evaluated and if no fetal pole
seen , termination is necessary.
As you have mentioned in your scan 3 masses are seen it could be molar pregnancy
of uterus or some blood clot. Typical findings of snow storm appearance of molar is seen in 3rd month not in initial days. grape like appearance is seen grossly not in ultrasound
If you get weakness, giddiness or bleeding needs to consult doctor
immediately. Otherwise not to worry.
Hope this helps you.
