pelvis pain 4 months pp

Hello! I had PGP whilst I was pregnant, and it disappeared after I had baby… I’m 4 months pp and for the past 2 weeks it’s back! I’m also really suffering with pain where just under my belly button. I can’t seem to get out of bed again I feel like I’m 9 months pregnant!! Anyone else had this ? I guess it could now be sciatica but is all in my pelvis 😬
