Please help me through this OCD storm: infant x rays

Female infant, 7 months, 20 lbs

Ok, so I know that I have trouble with OCD and it has really taken hold after the birth of my daughter. Yesterday, I thought she might’ve ate a button battery. There’s no way that she did. But my mind strung together all of these events until I was afraid she had. (I had gotten items out of a cabinet where they are stored and she was in the area on the floor. She had a coughing/gagging spell).

I couldn’t let it go. So I took her to the er. They did a mobile bedside xray (front and side view). Of course nothing was there. But this is a rural old hospital. And now I am in a loop of how I exposed her to radiation without need. Which is true. I did that. But I’m worried she will have cancer later because of me. I took something imaginary and cause actual real harm.

I’m afraid of the x ray and that they didn’t have pediatric settings or used it wrong. I honestly can’t believe I did that.
