Thanks Bex, but this still does not refute the fact that in empty sac miscarriages there is no embryo, nothing to become a human being.
Great picture, and it sure shows what is missing in the case of an empty sac: if you have a miscarriage at 7-8 weeks with an empty pregnancy sac, then that well formed 7 week old embryo in your picture is precisely what is missing. Let's look a little earlier:

. . . . <img src="http://herballure.com/ForumExtras/Images/hmamacujji.jpg">

Before 3 weeks have passed an embryo has formed within a pregnancy sac. All pregnancy sacs this old and older should have at least this much development, and it should be easy to tell that this or more is physically missing in the case of empty sac miscarriages.

And the earliest embryo stage is less than this. From: Human Development Chart:
The beginning of the embryo stage is at 14 days.

The earliest point that the pregnancy sac begins to develop is not much earlier than the starting stage of the embryo -- from Stages of Development:
Sac formation starts at day 10 to 12, just a couple days before the embryo stage starts. Every empty pregnancy sac miscarriage from 14 days to the 8 weeks of the statistics above should have a detectable embryo in side, and they did not.

All empty pregnancy sacs from two week to eight weeks that have no embryo are not going to develop one. There is no there there.

An embryo failed to develop and the empty sac is ejected.

All the conceptions in these cases of empty pregnancy sac miscarriages between 2 and 8 weeks fail to become an organism of any kind, and certainly they are not human lives.

No amount of emotional appeal will change that simple fact.

Enjoy.
