I agree with what everyone else has said hun. Get another scan done.

Not to freak you out, but I had a m/c in May and didn't have any bleeding or cramping (still haven't )... everyone is different and everyone's bodies react so differently when they are put under stress like this.

I had 4 early scans and didn't see a heartbeat until the 3rd one. It was at the fourth that we found out we'd lost the baby at 8w.

I completely understand you being resigned to the fact that your little one may be gone and for that I'm so sorry. I really hope the outcome is different for you.

When you find that manual, I'd love to take a peek

Big hugs
