anxiety

Little back story this is my first pregnancy and very desired but not EXACTLY planned. Just trying to see if anyone out there is constantly anxious about anything and/or everything going wrong? Still in first trimester (about 10 weeks), had first ultrasound w/ heartbeat. Idk if it’s because i work in medicine & have seen the worst of the worst, but i’m constantly just keeping it in the back of my mind that basically until 21 (ish) weeks, there is no guarantee. & even after that there are so many things that could go wrong. Im not emotionally struggling because of this, but it’s almost like a too good to be true mentality.

Anyone else have these thoughts in the back of their mind 24/7?
