Severe Pelvic pain (PGP, SPD) help!

I am having severe pelvic pain in the very front of my pelvis and it is radiating in to my hip joints.

My doctor mentioned taking a leave from work if I can't get it under control but I want to wait as long as I can before I stop working! I am only 27 weeks.

The pain is beginning to be debilitating and takes all night to calm down and then is back within 2 hours the next day and gets worse all day. I am waddling and want to cry.

Has anyone had success with any belts or products for this?

Hoping to order something off Amazon right away. Likely a plus size one.

Thank you glow family for help!
