Any ladies (TTC or did conceive) work in the dental field?

Okay I am a dental assistant and have been trying to get pregnant since July. I've had two miscarriages & can't help but wonder if it's related to X-rays, we do use a nomad regularly too, of course I stopped when I found out but during those 2 or so weeks I didn't know used it. (Although nomad exposure is minimal) I have a healthy 3 year old no issues with his pregnancy & I did not work as a dental assistant at that time.

Any thoughts in general about TTC in the dental world, thanks
