Horrible round ligament pain??

I’m pregnant with twins, 9 weeks, and my left hip at the back, shifts and pops out of place causing horrible sharp pain every time I walk. I talked to the doctor and she told me that it was normal until the second trimester because the uterus is pushing on it. It’s even worse for me because there are two babies instead of one. It does not get better with stretching, or back cracking, or walking. My family keeps telling me “it’s because you need to walk more”. Even when I’m out shopping or getting food, it does not get better, it hurts more because I’m walking a lot.

I don’t think they understand that this isn’t something that can just be fixed. I’ve been trying to use heat pads, stretching, sitting certain ways. Nothing is helping, and it sucks so bad. The only way for it to not hurt so bad is if I’m laying down completely flat with my back and hips straight. I haven’t been able to work the past few days because it has been so painful. Is there anything I can do? Or anything I can tell my family so they don’t think I’m just being lazy? It’s really stressing me out that everyone around me thinks that I need to just work through the pain when I physically cannot, it’s the most painful thing I’ve felt in a long time.
