I’ve got a band that wraps about your bump - I got it off Amazon for about £10 or something! It definitely gives some relief but I also find it really tight and I personally don’t find anything tight on my bump comfortable at all!
I am now able to walk 10k steps everyday due to my £10 belt from amazon after not being able to walk due to pelvic girdle pain
I bought a band off Amazon that let me and my boyfriend travel and explore Belgium, Bruges, Paris and more for a week so I’d definitely say get one. I also worked on my feet until 35 weeks x
