Oh sayang, ini memang situation yang scary dan confusing. Please go to your doctor or hospital again as soon as possible , the difference between the two scans needs proper explanation from your doctor, because only they can see your full medical history and scan images. A few of my mum friends went through bleeding during early pregnancy, and honestly, setiap case lain, sometimes it's just spotting, sometimes it's more serious. But the fact that your scans are showing different things is something your doctor needs to clarify properly, okay? Jangan stress dulu, just get professional confirmation. Take care of yourself and rest. You're not alone in this, but you need your doctor's answer, not google or forum guessing. Hang in there.
