Dear toktamf, In general, all laser hair removal devices emit a low-level radiofrequency field. Although it has never been proven that low-level radiofrequency fields will harm a foetus, as a young expectant mother, to try and minimize exposure to these types of electromagnetic radiation is probably a good idea. One option, if this is a job that you love and still require, is to wear a lead apron, which will shield you from electromagnetic radiation. These, however, are quite bulky and heavy, but will certainly provide the necessary protection. One can generally get these types of aprons from medical supply stores and stores that supply hospitals. I would suggest Googling “x-ray protective lead aprons for sale”. This may allow you to maintain a job that you might very well like. Best of luck as a young mother and I hope this information has been of some assistance.
