Help! Maternity activewear???

Emily • Mom of two 💙💗 #3 due in August! 💗 Work full time. Divorced but now with the love of my life.

Where do you get it that doesn’t cost an arm and a leg?!? It looks like Old Navy isn’t carrying it anymore because online inventory is XXL or XS. I’m 22 weeks and all my workout clothes (pants specifically) are becoming really uncomfortable. TIA!
