Pregnant after infertility & miscarriages?

Ashley • Avoiding pregnancy. 3 losses (6, 16, 15 weeks). 1 earth son, Lincoln born at 26 weeks. Just turned TWO & doing great!
I am finally pregnant for the 3rd time (no living children) after <a href="https://glowing.com/glow-fertility-program">IUI</a> #3 and scared to death. I also have a 6 wk and 16 wk miscarriage under my belt as well. This pregnancy has been so stressed as I am constantly having anxiety thinking the baby isn't ok  I'm going to lose another. This pregnancy took 2 1/2 years to conceive. I just feel overwhelmed. Anyone else experiencing anything similar?
