While it can be uncomfortable to get the waxing done (the laying on your back thing), if you usually like to be waxed, then you will probably feel better having it done than not. I know I felt 'tidy' and ready for my nether regions to be on display after getting waxed.

I can only say make sue you get a beautician that understands being awkward and uncomfortable in pregnancy and will give you enough time to recover on your side if you need it, without making you feel rushed. I had to swing over to my side a couple of times as being on my back was really sore towards the end.

Good luck with waxing and the imminent arrival of your bubba!
