There were so many things that I felt like made a such a difference in my pregnancy. I was glad others shared their suggestions with me, and I hope I can now help you by sharing what I thought was most beneficial! I also tried out a LOT of different maternity workout clothes, and have some awesome suggestions there!
Let’s start with my favorite options for maternity leggings & biker shorts. I was SUPER particular on what felt comfortable, & what fit well for each stage of my pregnancy.
I loved these CRZ biker shorts when I felt like I needed some more room, but I wasn’t quite into maternity sizes yet 
These amazon maternity shorts were AWESOME for my second trimester. The quality is great & they are inexpensive 
These maternity leggings are the same brand as the previous shorts, & they were so comfortable 
These Senita “Rio” maternity shorts were awesome. I loved the length, & they were super comfortable. I had them in a couple of colors, and was so glad I had them.

The Kiava maternity biker shorts were so great for the last part of my pregnancy. I think they run big, so the size I ordered didn’t fit with the panel until I was about 34-35 weeks.

I also LOVED these lulu align shorts. They aren’t maternity, but they stretched with me SO WELL, and were still comfortable. I’d definitely recommend them. These are the 8″ shorts, but I also have & love the 10″ shorts
As far as other items that I felt like were super helpful while I was pregnant, these were a few of my favorite things.
I love this oversized T shirt, and it is still a staple in my wardrobe. So soft, & went great with alllll the bikers 
I think everyone needs this nightgown/house dress. It’s the most comfortable thing I own & will continue to be worn into forever. 
These maternity swim bottoms were a life saver for me. I wore normal swim tops with these bottoms. 
I also loved this oversized tee from Aerie. Super inexpensive, & super comfortable. 
I put this belly butter on every single day of my pregnancy, & it helped me avoid stretch marks. I also found my skin got dry and itchy with pregnancy, & this helped avoid some of that too. 
This pregnancy pillow was amazing, and got me through a lot of nights. I loved this one because one side zips off, if you don’t want the whole pillow to surround you.
