Yes totally safe but u may want to do a test patch as your skin may b more sensitive now that your pregnant
Yes its safe. I just had mine done as well, doctor says should have it well ventilated bath room window and doors open maybe little fan blowing. I got mine done in the salon and it was ventilated well, just make sure if you'replanning on a salon and they put you under the dryer to take little breaks the heat can really get to you.
