Maternity workout leggings?

So my favorite workout leggings are the lululemon align tights and athleta’s powervita leggings. Both are a higher waisted legging - maybe to the belly button. I do CrossFit 3-4 days a week and am planning to up until I deliver. I’m 18 weeks pregnant and can no longer wear my athleta leggings because they are too constricting! I can still wear my lulus because they are a thinner and softer fabric so have more stretch, but probably won’t be able to much longer. I’ve looked into the gap maternity workout wear but don’t like how they only have full panel leggings. I’d prefer a low-waisted pair. I’ve been looking everywhere and am desperate for something I can feel good working out in! I’d take recommendations on shorts as well! What do you swear by??
