I panicked so much before my first pregnancy wax, thinking the pull or pain would affect the baby! But it is totally safe because the wax doesn't go beyond the skin surface. Just make sure the wax isn't too hot to avoid burns on sensitive skin.
Haan, you can absolutely do waxing during pregnancy, there is no harm to the baby. Just remember your skin is much more sensitive now, so it might hurt a bit more than usual. Go to a clean, hygienic salon and tell them to be gentle.
I am not a doctor, but I waxed regularly throughout my pregnancy without any issues. My only advice is to do a patch test first because pregnancy hormones can make your skin react differently. If you are in doubt, you can ask your gynac once.
I remember getting waxed right before my delivery date so I would be comfortable, and my toddler is perfectly fine today! It is totally safe, though the extra blood flow might make it feel a bit more painful. Just go for it if you feel up to it.
