spray tan

Hi y'all! I'm going on vaca and am going to be about 16 or 17 weeks preg by then and wondering if any of you spray tan around that time or even while pregnant. Just not sure if it's the best thing. I would go to the one where the girl does it to me. So it's not like I'm in a hot box with fumes around me for a certain amount of time. But still. Let me know! Thanks!
