I went it for my first check up at what I believed to be 7w2d. They saw no yolk, no heartbeat, and said the sac was measuring at abbot 5w5d and this was likely a miscarriage. They then drier blood and called the next days delighted that my HCG levels were 36,000 and putting me at around 6w5d. I then did follow up blood work 48 hrs later, and my numbers only increased to about 41,000. The Dr. said he is 99.9% sure this is a miscarriage. I would prefer to have a D&C and move forward, if this is truly not a viable pregnancy, but I need to be 100% sure. Is this 100% or is there anything they may have overlooked? Please answer quickly if you have any thoughts. Many thanks.
