Pelvic pain increasing

I am 5.5w pp and my pelvic pain seems to be increasing. I cannot stand from sitting without pain and if I’ve been sitting awhile, I need help to stand. It’s like sharp pains through my tailbone, hips, and lower spine. I’ve also been getting a lot of cramping. Feels like terrible menstrual cramps. I am breastfeeding so it shouldn’t be my period just yet although I know there is a chance. My pp bleeding only stopped a few days ago though.

Anyone else experience this? Also my cervix feels low and I feel like there is a balloon in my vaginal canal, bladder side. Is this possible prolapse? My 6 week pp check up won’t be until I am 8w pp due to holidays, so almost three weeks away.
