Unfortunately, I just had the very same thing happen. I just hope your outcome is different than mine. My LMP was July 1rst. I went for a check up and should have been 8 weeks (a little over 2 weeks ago). and couldn't see a baby or heartbeat. They said I was only measuring about 6 weeks prego. I had to go back for a 2 week follow up (last week) and unfortunately the pregnancy still measured 6 weeks. I had to have a D&C on Friday. I really hope that your case is better. It could be that you ovulated late, I will keep you and your baby in my prayers. IF you need someone to talk to, I am here.
