Any dental hygienists?

Hey! I'm wondering if there are any dental hygienists out there who are pregnant. I am 7 weeks pregnant with my first and have not told my employer yet (waiting for doctors appointment next week). My question is... what are your thoughts on taking X-rays while pregnant? I make sure I am always out of the room and behind a wall when X-rays are exposed but ever since I got pregnant I am nervous about exposure.
