Hip Tightness

I'm just wondering if there's any other moms to be with extremely tight hips.. my upper leg area that connects to my groin area is so tight and painful it hurts to walk stairs and I usually can't sleep in past 6am due to the pain of them feeling compressed from me side sleeping all night.. I'm currently 21 weeks pregnant with my second.. this didn't happen to me with my first. I'm pretty physically active, I do yoga almost daily but no matter how much I stretch my hips are still so tight.. is anyone else dealing with this??
