Suggestions needed!

Ok preventative measures for hip pain needed. I'm 23 w 4 d with number 1 and my hips are killing me. I work full time at a very physical job. I spend a lot of my day lifting and bending. Carrying heavy boxes (I've limited myself to less than 30 lbs and try not to go over 20lbs if I can avoid it and my coworkers are great at helping out) and constantly being on my feet. What can I do, besides working less, that will help? I take warm showers and baths and stuff and the occasional Tylenol when it's really bad but those things only help after the fact. Any suggestion is a good one! Thanks!
