what were your must-haves during the 2nd trimester?

Sara • MC 10/2015 at 4 wks & MMC 10/2016 at 8 wks + 2 days. Currently pregnant with my rainbow, due 11/2. 🌈
Looking for recommendations- specific clothes, bras, pillows, lotions, supplements, exercises, etc, that you couldn't live without during your second trimester? I'm feeling gross and uncomfortable, lol!
