Anyone else just uselessly anxious

I don’t know what happened last week - I was breezing through this pregnancy and feeling good anxiety wise. I was miserably sick w morning sickness 24/7 but felt good about our little guy doing well. All tests have come back normal, our anatomy scan was fine and then last week I got a touch of a stomach bug for a couple days and since I’ve been anxious and convinced something is wrong. I haven’t had any alarming symptoms - no bleeding or leaking fluids that I’ve noticed (and I definitely keep track) and baby is still moving and active but I just cannot shake the feeling that something is going on. Anyone else? Is anxiety a reason to call the Dr - I feel like some reassurance would be amazing at this point in time....
