These Hips don't lie- they CRACK!

Hey ladies! Just curious if any of you are experiencing hip issues? Since 9 weeks both hips have been giving me different fits. My left hip has serious pressure built up like I need to pop it -- but it never pops. Instead everytime I step the pressure builds more and spreads to my cheeks with no relief. Stretching does nothing. Eventually(2-3 days later) it relaxes. My right hip-- that sucker just cracks when I adjust my sitting arrangement. It's painful and sharp but slowly dulls away.  Is this due to the relaxin?
