chemical pregnancy???

I had been feeling pregnancy symptoms and all kinds of signs. I never got my positive but my "period" came late and I was in excruciating pain. I've never had cramps like that I couldn't get up and I was clotting a ton but then after one day it was gone. Is this possibly a chemical pregnancy? And has one ever had one where they felt like they had seriously  lost a child. I'm not sure how to feel right now... :( I feel like my SO isn't as upset by the possibility as I am so I'm not sure if it's Normal to feel so upset about this.
