Scared of pregnancy and childbirth

Anyone else scared of pregnancy and childbirth? I’m almost 17 weeks and have had three previous miscarriages. I’ll be 40 at the time of delivery and I also have a blood clotting disorder which I am on Lovenox injections for. I’m high risk and that scares me even more. The 20 week anatomy scan scares me, dying during childbirth scares me, stillbirth scares me.. pregnancy is scary. It’s a wonderful thing but growing a human is also not simple and I wish our society talked more about the anxious part of it and allowed women like me to feel better about being nervous. I think it’s normal but I just want to know how other women who worried got through it and what helped to calm your nerves. My husband doesn’t get it because when I try to express myself all he says is it will be ok. I appreciate his support but all I want to do is vent. I’ve read that the US has the highest statistics in mortality in childbirth so that definitely doesn’t make me feel better.
