Athletic maternity leggings and tank tops?

I have a few pairs of Blanqi tights and Senita Athletics tank tops from previous pregnancies and was hoping to get a couple new pieces for later this pregnancy, but everything shows as sold out for Blanqi AND Senita went out of business. Yikes! I had tried a pair of leggings from Old Navy in the past, but they were too restrictive for strengthening, running, and yoga.

Anyone know of where I can currently find athletic/supportive leggings that also allow freedom of movement? Also, any recommendations for athletic tank tops with a good bump fit (not weirdly short or loose at the bottom)?

Thanks in advance!
