Hi I Am 3 Weeks Pregnant And Been Having Little

Hi
I am 3 weeks pregnant and been having little cramps every day. Yesterday night I had a severe cramp that woke me up. When I woke up this morning I couldn't feel anything, all the pain was gone? No bleeding but I feel empty. What are the chance that my pregnancy is over? Do I still have a baby in my tummy or is dead.

Thanks

Isa
