X-ray and possible pregnancy :(((

Two days ago I got a chest X-ray, I wasn't feeling good and I had some breathing difficulties.

They asked me if there was any possibility of me being pregnant: I told that there was because I wasn't preventing.

They made me an urine test and it was negative ( but I felt it was quite stupid because my period was due in 3 or 4 days and it could be a false negative).

They told me not to worry because the test was negative.

I got this x-ray and they didn't use the protective shield.

Now I just can't sleep thinking about the possibility of being pregnant.

I feel terrible because I feel that I was very stupid , I knew that the test result could be a false negative and I didn't have the courage to tell them that I was afraid of the radiation.

I'm really stressed because I suffer from endometriosis and getting pregnant is quite difficult.

It would be terrible if I really was and I have harmed my future baby.
