Hip pain?

Victoria • 22. Viviana’s Mama.
I am 17 weeks pregnant and noticed that whenever I work long shifts or walk too much throughout the day, at night my right hip starts to hurt. It's not necessarily just my hip but also the upper right side of my thigh and the ride side of my lower back. 
Is there any solutions for this? 
The pain comes and goes, sometimes it's bad to the point where when I stand up to walk my right side is stiff! I also have already purchased a pregnancy pillow too
