I'm on day 2/3 of miscarrying at 8 weeks. The hospital said that it was only the size of 4-5 weeks though. I'm sure this will sound ridiculous, but I hate the thought of it just coming out and disappearing down the toilet and me not even knowing whether it is still in me or not. So, would you know when an embryo of 5 weeks comes out, or might I have missed it already?! Sorry.
