Aiyoo sayang, I know how scary that must be But since you've already been to the ED at HKL and the doctor said baby is normal at 6w5d, that's actually good news, at that gestation, sometimes the heartbeat might be harder to detect on scan, it doesn't mean something's wrong. Since you had bleeding though, you really need to follow up with your gynae as soon as possible to check on the cause, please don't wait, yeah? A few of my mum friends had similar scares early on and their doctors sorted it out quickly. Go back to your OB-GYN for proper follow-up, okay? Take care of yourself
