Ct scan 5 weeks 6 days Pregnant

Ashley • Her children arise and call her blessed; her husband also, and he praiseth her.
Had to go to the ER in the middle of the night with severe chest pains. Ruled out heart problems, heartburn, and reflux. They ended up having to do a Ct scan. I am so terrified because I know the risks with this being my fourth baby and I'm still in my first trimester. I was shielded pretty good but should I still be so worried?
