laser removal dangerous during pregnancy?

Hello, I have some facial hair that I have been fighting with for years. It has come to the point where it interferes too much with my life. I would like to try removing it with laser. But I am planning on becoming pregnant soon. I have read that laser epilation is contraindicated during pregnancy. Is there a risk? why? I thought that maybe I could go along with both, since the area to treat (face) is so small.

I would be grateful if you could advice me on this.
