What should I do( pretty long)

So my husband and I have a 2 bedroom apartment and there was 4 grown adults(Friends) staying with us( now it's down to 3) so a total of 5 people in the house(they were all supposed to be gone yesterday) plus our dog. It's a long story but at the time They had nowhere else to turn and we had empty space. They said they would pay us $1,000(rent is almost 2,000 anywhere you go over here)& the person that was supposed to pay us is gone🤔. I honestly could care less about the money it would've been nice to know if they couldn't though because we planned on putting that towards the baby. But I am beyond frustrated!!! I'm almost 29 weeks pregnant and shouldn't be cleaning up behind grown ass adults & I shouldn't have to tell them to clean up everyday. And on top of that I told everyone to stop smoking in the house but there is one that I'm letting stay in my baby girls room & I come out of my room this morning and smell cigarettes(the smell disgusts me and I don't want a disgusting house) so that ticked me off!! Do not smoke in my baby girls room.I felt that was very disrespectful & my husband told her to stop literally 2 days ago(yes she did this 2 days ago) but it's like it went in one ear and out the other. I am the only person cleaning this house because I just can't sit in a dirty house especially now that our baby is going to be here very soon. I clean EVERYTHING when it's not my mess, I'm in my room all day everyday. My husband says he'll clean but he works literally all day and I don't want him coming home to a dirty house. They were supposed to be gone yesterday but won't be gone until the 6th and didn't tell us until we asked like don't just expect to over extend your stay and not tell us like we don't have life going on too. My baby's furniture comes Friday it would've been nice to know! They are literally stressing me out when I don't need to be stressed at all and while we're being nice and letting you stay in our house when we don't have to you should follow the rules. The only rules are to clean up and not smoke in the freakin house but that seems to hard to do for adults somehow. It literally hurts me to clean now so I've just been doing what I can, but I've been nice for too long.I have one more week left of this but I really want to kick them out today because I feel very disrespected and the stress is starting to manifest itself physically and my baby and I don't need this. Debating what I should do.
