Need some help

I have never had a wax before. I have alway(since my divorce anyways) taken care of myself when it comes to hair. 
Well now that I'm 18-19 weeks preggo I cannot seem to reach the necessary places. Lol I know that sounds weird but my belly get in the way and I have a really bad hip and can move it in certain directions. 
Any advice, suggestion? I've tried a mirror and that failed too! 
Short of asking my bf for help I'm stuck!
