Extremely painful bowel movements while on period.

Hey, I’m wondering if anyone has experienced extremely painful bowel movements while on their period?

It don’t feel like it’s constipation because it’s still soft, but my belly bloats sooo much.

I get shooting pains basically from my asshole right up to under my boobs.

I can’t sit down, moving from a sit to stand is incredibly painful.

It usually lasts for about 3 days, but only ever happens on my period.

I have endometriosis, so I’m used to pain... but this is next level. Can’t breathe, can’t move... just have to wait for the pain to pass.
