Belly bands/ support?

Do you think they help or make a difference at all? I think a muscle is tearing on my side, probably because I’m still horseback riding at 5.5 months pregnant. It’s a stabbing pain always in the same place... I’d love to hear any feedback if these worked for you! if I can continue to ride comfortably I will! If not I’ll probably have to stop very soon. What brands would you suggest?
