OH NO I NEED ADVICE!!!!!!!!!!

OK SO!!!

I just moved into a new place.

I had a bath the second night.

Heard gushes of water coming from basement (it’s unfinished.) I look down; it’s flooding and the smelliest of shit ever !!! I go down and look and the sink down there is filled with tp and poop!! Now the smell is throughout my whole house!

Plumber cant come till the morning.

Question is ... I am 30 weeks pregnant and have a 4 year old, are we safe to stay here? Should landlord be paying for a hotel ? I cantget the smell of Shiet out of my nose I am so very grossed out. I don’t know the first thing about plumbing. Pictures attached. PS YOU HAVE NO IDEA HOW MANY DRY HEAVES I HAVE DONE THE PAST HOUR.

EDITED: please note that this happened around 4:30 pm. 8am is when plumber is supposed to come. SHOULDNT THIS BE DEALT WITH IMMEDIATELY? Instead of spraying some febreeze! This is a serious health issue! Is it not?????
