Thanks for your query.
At 6 weeks, cardiac activity is normally seen on the ultrasound
Multiple perigestational hematomas significantly increase your risk of having bleeding and undergoing a miscarriage
A regular sac is a good prognostic sign however.
THe only way to tell which way your pregnancy
will proceed is to have a repeat scan after a week as suggested.
Till then, take adequate rest, avoid stress
, exertion and intercourse.
take the medications as prescribed.
All the best.
