Severe cramps, help please

So i woke up at 4am with severe cramping in my abdomen, and in my back. It felt like period pain only worse. It goes away after a few minutes, then its a dull ache, then 10 mins later it comes back. Theres no bleeding but i havent experienced cramps like this before. Im currently 9weeks 3days pregnant. I suffered a mmc before at 6 weeks. Please help :(
