Pregnancy Anxiety

Did anyone else have major anxiety about baby? I am always so worried she’s not ok, and the 4 weeks between my appointments feel like forever. I am 16 weeks and the few symptoms and food aversions I had my first trimester are gone now, plus I don’t really have a bump at all so I feel and look just like I did before I was pregnant. I know I should feel ‘lucky’ for feeling this good but it’s just honestly giving me anxiety to the point where I’m like in denial that there’s even a baby growing in there.
