So anxious about a miscarriage

I had 2 miscarriages before I had my son a year ago and now I’m pregnant again. My anxiety is through the roof. I can’t get excited about it and I’m operating like I’ve already lost the baby and when I go to the doctor in 2 weeks, it’s just to confirm. I haven’t had a lot of pregnancy symptoms like I had with my son. I do have to eat every 1-2 hours or I get nauseous and I’m more weepy than usual but I just don’t feel pregnant. Anyone else having this issue? I keep googling the statistics on miscarriages after live births and there isn’t a lot. I just need some support. I don’t know a lot of people who’ve had miscarriages and I don’t know anyone whose had a miscarriage after having a baby. 😫
