Miscarriage anxiety

I had a miscarriage at just over 11 weeks back in may and lost my twins. I am pregnant again and am now just over 11 weeks. This pregnancy is going well with no complications just the normal all day sick feeling. I’m just terrified of losing this precious baby. Now that we are around the same time I can’t shift the feeling that I may lose it. It’s not rational because there is nothing wrong but the anxiety is overwhelming. It hasn’t helped that both my husband and I had the same nightmare last night that we lost it. I was holding little one in my hands like last time. It was so real. How do I get through this anxiety? How can I stop worrying? It’s constantly on my mind. Does anyone have any coping strategies they can share? I’ll try anything. Thank you in advance x
