These aren't really maternity shorts, but I wore them a lot around the house the last month or two of my pregnancy. The waist band can go over the bump, and on me it went to above my belly button.

I also had these that my mom bought, they're over the bump. I mostly wore then in the pool.

I wear these to work out in as it's hit high 80s here this week and leggings aren't cutting it! They're not the best shorts I've ever owned, but they're decent. I'm 31 weeks and they still fit, they have an adjustable elastic at the top. I'm not comfortable in under bump shorts anymore, as I do a lot of movements that cause my shirt to lift up a bit and I just feel weird about flashing my belly at the gym even though I know they don't care, lol!

I am 34 weeks and have a pretty small bump. I remember being around 16 weeks when you’re too small for full panel maternity but too big for the side panel to fit correctly. My recommendation is don’t invest too much money in the side panel. I wore them for a very short time period and in a couple weeks you will quickly find the full panel are way more comfy. Like I said, my bump is small and that was my experience... if you end up with a big bump then you will need the full panel even sooner. I live in FL where it is hot hot hot right now and I wear my full panel everyday. I highly recommend you check out eBay for maternity side panel pants and shorts if you end up buying some to save money. I wore a size 10 and I do not have a lot of butt lol I love the way H&M and ASOS bottoms fit, they are very flattering, especially if you like more skinny jeans and fitted/non baggy shorts. I hate how loose most maternity shorts and pants are!!

I also bought these shorts on amazon and absolutely LOVE them

Have you tried button down maternity tunic? It is pleated waistline, which can offer big space for your bump: https://www.amazon.com/dp/B07TB52QP7/ref=sr_1_4?m=AO8A8TJ6SLFIQ

And this Motherhood maternity short is very comfortable:
