I'm currently on my period and use a mooncup. When I took it out to empty I noticed that there was something was in the blood. I poured the blood onto my hand and looked at it. There was a grey piece of I don't know what, it was about 1cm square and it looked like cells packed next to each other do. It felt kind of jelly like.
I tried to find a picture of something similar on googleimages without luck.
Does this sound like it might have been a miscarriage?
This is how Oxbridge students do it.
