Anxiety with my pregnancy.

I've had 3 miscarriages in the last 2 years. We found out last Tuesday that we're pregnant again. Blood test confirmed it. I'm scared for our child's life. I haven't made it past the first few weeks with my others. I'll be 5 weeks tomorrow. Please pray that I have peace. That what ever happens, I'll give God the glory. I know that no life is ever worthless and that there was a reason that my first 3 were conceived, but my soul aches for their loss. And...I'm not sure I can deal with another so soon. Thank you.
