I'm out
I got my 7w (7+0) scan today, and the development was very far behind (the nurse didn't say how much, but to me it looked like 6w max, maybe even 5 looking at you all's pictures). No heartbeat. I will have to go back in a week for another scan with a doctor (probably to understand how to move forward, since I had no bleeding).
Best of luck to all of you here. We know that the chances are only 70-80% from a positive pregnancy test to a baby, but it was still heartbreaking. Keep positive and I wish all a happy, healthy pregnancy!!
