Nervous about first trimester!

Jennifer
I had a miscarriage in July, and my husband and I have been TTC. I got the great news that I'm pregnant and I am four weeks along. I want to enjoy this pregnancy but in the back my mind I'm worried that I'm going to have another miscarriage. Every cramp, sharp pain I'm always wondering is this it.  I just want to hear from some moms that went through a miscarriage, and now they are either pregnant or have a child. Did you feel the same way. I need some words of encouragement.
