Am/was six weeks pregnant and have been bleeding for 3 days now, went for ultrasound today where they found no baby but I still tested positive on a urine sample they did at the hospital. The nurse seemed to think this is unusual so they took blood to test HCG levels and will do another blood test in 48 hrs...what's going on do you think? Is it likely to be ectopic or is it that my hormone levels just haven't sorted themselves out yet? Thank you!
