WIBTA if I cancelled on him staying?

I have a friend staying til Sunday, he arrived last night. I’m already regretting having him stay and I’ve also agreed for him to stay again in 2 weeks (both visits are for work). It seemed like a good idea when we made the arrangement a while ago but I’m 34 weeks tomorrow and I think I’m just too cranky and pregnant to be hosting 😅 he got on my nerves almost straight away and I really want to get on with sorting the baby’s room and hospital bag and just be kind of left alone atm. WIBTA if I cancelled on him for his next visit in 2 weeks time?
