I saw the baby's heartbeat (strong 160 beats) at my 8 week appointment. At my 12 week appointment, the doctor couldn't find a viable embryo, only debris in the sac. I opted to let nature run its course, but my doctor wanted to see me each week to keep tabs on my progress (or in my case, lack of progress). At my appointment the next week, the sac had grown, but still was completely empty. At my next appointment (would have been 15 weeks) the sac had again grown and surprise! the baby was in the sac with a visible head and arm/leg nubs. My doctor made very very sure that the baby was dead. My question is: Where the heck was he before and why are we seeing him now? It was horrible!! My body still hasn't gone through the "miscarriage" process, so I am having a D & C next week.
