I'm 29 weeks and this has been going on for a few weeks now. Now it's worse than ever. My hip makes a popping sound too. It's always the right side like deep into my butt cheek. Sometimes I can rub it out and other times it wants to drop me like my leg and hip is giving out. I'm convinced my hips spread earlier than normal and my sciatic nerve is being pinched. I can hardly stand sit walk or even lay down. Baby girl is head down and has ALWAYS been lying very low. A lot of pressure. She's 2.5lbs right now but feels like 20.
