Gynae doesn't allow HL even when I'm having left plevic pain for quite a while.

My gynae doesn't allow me to take HL until 37 weeks. I'm currently 32 weeks .I'm suffering from pelvic pain on my left side causing me to have difficulty walking normally or sleeping. I got to wear the support belt to help me with walking. My jobs require a lot of bending or walking. Anyone facing some issue with pelvic pain ? When should I be concern if the pain persists #firsttimemom
