Retained placenta? Should I go to the hospital

I’m one month pp

Stood up to get the baby and have a hush of blood clots. I’ve been passing clots/blood for a entire hour. Just passed this, it’s hard feeling. Should I go to the hospital?

Update- went to hospital waiting for doctor

Update again- have more tissue, they gave me a pill to try to get the rest out, if not they’ll have to give me a d&c
