Pregnant and working on my feet doing hair

Help I’m 27 weeks pregnant I do hair and constantly on my feet , should I be concerned ? That I rarely rest now so how will I rest when I need to feel movements if need be ? Or will I end up feeling them when I do hair ? Feeling concerned if not allowed lmk sorry just need advice from we’re pregnant moms who were like me and did hair :( http://americanpregnancy.org/while-pregnant/kick-counts/ this is crazy I dont rest nearly enough to be able to do this :(
