I fell pregnant in the middle of mine and they told me that while they consider it safe they don't do it for pregnant women because results cannot be guaranteed due to hormonal changes affecting hair growth. I stopped mine and they agreed to carry over my session until I give birth and am done breastfeeding
I've read conflicting reports about whether it's safe or not (I was home lasering with a Lumea prior to getting pg). I've given it up just to be on the safe side but it does make those early sessions seem like a right waste of time and bulb!
I would for now!! It's such a new thing that evidence can't be that strong! No only that, you do grow extra hair so you might find you'll be wasting time and money!! Be like the rest of us, hairy men!!
