Please HELP - Irregular gestational sac and subchorionic hemorrhage

Sou

5 week 6 days. I had heavy bleeding and cramps and admitted in hospital. O/E cervix closed. On transvaginal scan irregular gestational sac found. Yolk sac is 0.19cm and fetal pole seen.. fetal cardiac activity was not seen. subchorionic hemorrhage was tge xause of bleeding. But told more concern is about gestational sac shape. He said wait for 1 more week. Scan after 1 week will tell whether to continue with the pregnancy or not. i am really worried. Does someone have success stories with same issues.
