Sayang, I'm so sorry about your loss, that must be really hard Tapi please see your doctor or go to the clinic ASAP to discuss this, okay? High Hb levels after a miscarriage boleh ada different reasons, and a doctor needs to check what's actually happening with you, bukan something to figure out sendiri. They need to do proper tests to make sure you're okay. Don't blame yourself lah, most of the time these things happen for reasons beyond our control. Mesti kena professional check dulu before thinking about the why, ya? Sending strength to you
