Endometriosis after pregnancy

I was hoping to get some information on people's experiences with pain postpartum. Since having my son 4 months ago I wasnt experiencing pain, even with my period returning 1 month postpartum. Now I'm 4 months PP and I had another period but I had some pain, it wasn't as strong as before, but it was enough to get me to go home when I was hanging out with family.

I'm curious how it has been for other women PP with endometriosis and should I expect it to return full force?
