Jenna Haze is getting emergency medical care after posting alarming and bloody images of herself, which prompted an early morning visit from cops … TMZ has learned.

Early Wednesday, the retired pornstar’s IG stories were filled with photos and videos showing blood dripping from a wound on her hand. She also showed herself coughing and spitting up in a bathtub.

Jenna really set off alarms for her followers when, in one video, she accused an ex, saying, “Before I die, I want every single person to know the abuse I suffered.”

L.A. County Sheriff’s Dept. tells TMZ they got several calls to do a welfare check on Jenna, and deputies did go to her home just before 5 AM. We’re told an ambulance took a female patient to the hospital.

It’s unclear what Jenna’s condition is right now. She has posted a lot in the past about mental health advocacy and recovery.
