Tiffany, instead of crushing completely, can you break it in half with your finger nail or a plastic card of something? That's what my boy's get.
Also Meeple, looks like a boy but I can't be too certain since the ventral's don't look very long. If you could get a flashlight and shine it behind your baby, see if you can see triangular ovaries behind the stomach. something that might help is to stress it out a little, put it in a cup or something that it doesn't like so it can lose color and that should make it easier to see if there are ovaries or not.
