First period after m/c

I had my second miscarriage a month ago. I was 5w3d only, so physically it wasn't bad at all. I even ovulated 2 weeks after m/c and now AF arrived yesterday, right on time. So everything seemes to be normal again (which I'm so glad about), BUT... I have the worst period cramps! 😩 I am in so much pain most of the time. In my opinion, this is worse than the actual miscarriage (or my previous miscarriage at 10w2d earlier this year). 😱
I understand that first period after m/c is never "normal", but I thought it's about the heavyness of the flow. 
Did anyone else also had awful cramps after m/c? I don't remember it being so painful after my first m/c...
