I'm very sorry that you're going through this and although I can't tell you what's normal and what isn't, I can only share my experiences when I had a miscarriage at about the same as you.

The cramps were very bad and I had to stay in bed for a day and a half. They were much, much worse than period cramps and having since been through labour, I have to say that they were much sharper and yeukier than being in labour (even though it was relatively an early miscarriage).

I bled for about six weeks afterwards.

I did go to hospital and they said that a D&C wasn't necessary as my body was dealing with it on its own.

But if you're concerned, do seek further medical advice.

Once again, I'm very sorry that you're going through this. Words are never enough in a situation like this sweetheart.
