Hi Poppi,
Big congratulations, that is so exciting. 6w2d is very early, and still too early sometimes to check for heart beat. We had our first scan at 5 weeks which showed 2 sacs, the second scan at 6w5d, which showed two heartbeats, I so hope you see the same. I have heard it depends on the position as to whether your FS can pick up heartbeat at this early stage. Your hcg levels are great, so you are in with a really good chance. Sending you all the best and will have my fingers crossed for you for scan on Friday .
