First trimester anxiety eating away at me

I’m constantly worrying about having a miscarriage. I find myself spiraling and wondering if my baby is gonna be ok and make it through until it’s time to give birth. I work at a hospital and I have to be on my feet constantly and help lift patients. Idk I’m worried the strain might cause something bad to happen ;(

Mt first ob appointment isnt until this upcoming Wednesday and I’m freaking out because I have no way to tell if I’m still pregnant or if I didn’t have a miscarriage or if I could potentially have one in the future. Even after the first appointment all they can do is a blood test and urine so there’s not anything else that’ll be done. How do I decrease this worry and fear surrounding making it out of the first trimester???
