Aww, sy paham, ni memang period yg mencengangkan lah Honestly, heartbeat biasanya nampak clearer after 9 weeks, so don't lose hope yet, a few of my mum friends went for second scans and baby's heart was beating fine, jadi jangan risau sangat dulu okay. For a tilted/low uterus macam yours, most doctors akan suggest avoid heavy lifting, rest more, and maybe pelvic rest depending on your situation, tapi since your doctor mentioned high risk, better to check back with them on specific dos and don'ts for your case, sebab setiap pregnancy lain. Doakan yang terbaik, and sy harap scan berikutnya will bring you good news! Take care of yourself
