5 weeks pregnant and having pains :(

Kirsty
I had a miscarriage in March this year at 6 weeks. It literally broke me. And I didn't think it would happen again. But I've just found out I'm 5 weeks pregnant and terrified that it will happen again. I've started having mild shooting pains in my vigina. And had really bad painful cramping in my back and belly. Is this normal? There is no blood.
