B Belly and SPD?

Jessika
I have PCOS and have had a B Belly my whole life. I was recently diagnosed with symphsitis and my doctor suggested a belly band. However, this is baby #4 and my belly has never ended up rounded because of my B Belly. I purchased a belly band and I have it on now for the first time, but it feels like it's just pushing on my uterus instead of lifting it up. Will this work to relieve my pain since my belly isn't that big where the band is supposed to be lifting it or am I just making making myself super uncomfortable right now?
