Hello, A Couple Of Weeks Ago I Went To My

Hello, A couple of weeks ago I went to my local urgent care clinic because of constipation and sinus issues. I told the nurse theres a chance of pregnancy she replied ok then took my urine samples shortly after sent me for a xray one of my stomach standing up and another laying down on the table. Then the doctor comes in and tells me i tested positive for pregnancy after two tests low hcg levels may determine early pregnancy i believe my hcg levels were 37 or 57. Now im worried that my unborn child may have affects from the xray I am sad and angry. What should I do why did they not wait before sending me to get an xray not one but 2 xrays?Thank you
