is it ok to wear the box for a digital radio aid when pg?

[olivo]

i teach some deaf students who wear hearing aids for which i wear the little box and microphone. is this safe when pg, does anyone know?
it would be extremely awkward if i had to stop using it as i am only early days and don't want to tell anyone at wokr yet, but I am not going to put the baby at risk.

bump - in case any of the evening crowd can help!

nothing in the instructions of mine warning against it!
hth.

thank you notcitrus. that does help.
