Weird pain in left hip

Cynthia • 20, engaged and ttc.
I do not know what it is . It just started today and it goes from the left side to the right side. It's a weird dull achy feeling in my hips . And kinda makes my legs achy too. Please give some input , I am so incredibly scared that something could be wrong. Any input ladies ? I read about round ligament but I think I'm too early for that. I'm only approx. 5 to 6 weeks.
