waxing in the first tri?

So, a special thank you to my prenatal vitamins, but my upper lip is getting a bit hairy. And by a bit, I mean I feel like Chewbacca's long lost sister. My sweet, loving husband actually noticed it. 

That said, I used to get my upper lip waxed once a month or so. Is it ok to still get waxed in the first tri?
