Postpartum day 5, 3rd degree tear, help.

I finally had a bowel movement after giving birth last week and it wasn't as bad as I thought. Then, suddenly standing in the kitchen today I felt myself pooping in my pants! I had zero control over my butt muscle to stop it. I tore 3rd degree to my bum. Is this normal? Does it go away? Call the doctor? I'm so embarrassed 😫
