I'm currently 6w3d and had bleeding (with fresh red blood) for a few hours last weekend and quite a lot of cramping all last week and was convinced I'm having a miscarriage. I got my HCG levels checked and it was 40000 then 53000 after 48 hours and am just wondering what these levels mean? It seems high but not close to doubling. Has anyone had similar and gone on to have a successful pregnancy? I have a scan in 5 days but the anxiety of not knowing is killing me and making it hard to sleep or concentrate on anything.
