I'm sorry to hear you are going through this. I have not been fortunate enough to find the doctor to be wrong. In the past 4 years, I've had 7 pregnancies (2m/c, 1 daughter, 2m/c, 1 daughter, and my last m/c 3 weeks ago). My most recent m/c... appeared to be developing fine with good numbers. I was taking progesterone suppositories for the first time with this pregnancy which made me feel much stronger pregnancy symptoms so I couldn't go by symptoms to reassure myself of anything. At 9w2d, I had an ultrasound (of many) which showed the baby measured 9w4d but no longer had the heartbeat we had seen before. We scheduled a follow up for a week. It seemed like a long time but I hoped that maybe they were wrong. The longer I could push off that follow up, the better because to me, I was still pregnant. Unfortunately, the Dr was right and the baby still didn't have a heartbeat. I was given a choice and I chose to have a D&C a couple of days later. I did not take a pregnancy test nor have blood levels drawn at the end so I don't know if they still showed I was pregnant. Once it was definite that the pregnancy was over, I just wanted it to be over. I wanted to begin to heal and try again. My first pregnancy also ended in a D&C. At that time, I was 12w3d and my symptoms had subsided which I thought was normal. I was not on any meds other than a prenatal vitamin. The baby was measuring 9w3d and no heartbeat. The Dr I had at that time told me that if I had taken a pregnancy test, it would be negative. I didn't check. All of my other m/c were natural. All different. All before 6.5 weeks. I've had positive turned negative HPTs before bleeding started and I've had it where I had heavy bleeding for days with a lingering positive HPT. Although it hasn't happened to me, I have heard of miscarriages being misdiagnosed. I wish you luck and you'll be in my thoughts.
