You can actually do all of those things. Some recommend not dying your hair in the first trimester just in case though. Also make sure your in a well vented area and if you want you can wear a mask.
Waxing is fine, I thought I heard some sort of guidelines for it but I'm not sure. I do my nails, always have and haven't had any issues, and color your hair in a well ventilated area, I've heard bleaching is bad. But if you're really concerned. Ask your OB or midwife (:
I can't go without getting a facial wax, my hair grows back fast and thick.... mostly on the face. Not a good look :/
Thank you girls, greatly appreciated! Don't know what I'd do without any of those things, especially the waxing!
