Honestly mama, during pregnancy I just stuck to trimming with scissors or a small electric trimmer, safest option lah since you can't really predict how your skin will react to waxing or creams when pregnant, kan hormones everywhere! A few of us mum friends also did the same thing because we were worried about infections or irritation down there, plus your skin gets extra sensitive. Best to check with your gynae first though, because some doctors okay waxing if done by a proper salon, but everyone's pregnancy is different, better safe than sorry lah! After you deliver and if you're breastfeeding, I'd still give it a couple months before trying anything too harsh on that area.
