Reaching your loss week

Hey ladies! I had a late loss of our son at 16 weeks in May. I found out I was pregnant again in October. I’m getting so close to the 16 week mark and the closer I get the more scared I am I will loose this baby. How did you cope during your rainbow pregnancy? Does it get easier once you get past this milestone? I feel so defeated and hopeless. I have no signs that anything is wrong, but I didn’t last time either so it just doesn’t reassure me. I should also mention that with the loss of our son we did lots of testing and everything came back normal so we have no explanation of what happened to cause it.
