Shooting pains in my butt

Brittany • Mommy to a wonderful 12yr old boy, 9yr old boy 7yr old girl 6yr old girl and 3yr old girl. Due March 11th 2023 with a boy.
Anyone else have this? I've been able to go poop no problems since right after I had my little girl. She is now a week old and the last couple days I've been getting sharp shooting pains when I feel like I have to pass gas or when I have to poop. It's sucks soooo much :-(
