Sensitive subject. (Mc)

There are so many women on Glow that have had MC. I did not realize how common it was. I have never had one but I was wondering if you feel it? If so, what does it feel like? Or do you just wake up bleeding? Is the bleeding different from your period? 
​I am sorry if I sound insensitive to the people who have had a mc. I am just wondering.  
​Also, to the women who have had one, I am sorry for your loss.
