Little Help Ladies

Hello,

This is my second pregnancy but I miscarried in my first.

I am so scared I have another miscarriage every twinge I get I'm scared I'm going to bleed again.. has anyone been through this and found anyways that make you relax a bit? Can I ask my doctor to measure my hormones for me for peace of mind? I'm only about 3 weeks and miscarried at 6 weeks last time.

I'm going insane and I k ow I have to be patient and stress isn't good for pregnancy but I just cant seem to switch off.
