Help pleasee

I’m 21 weeks 5 days with baby #2, my SO works out of state for three/four weeks then comes home for one week, and I stay with my parents for the time being, well I just finally found a place to rent after searching for MONTHS! It’s right next door to my MIL (a Godsend, she wants us to live there and she would be so much help with a newborn and a toddler) it’s 2 bedroom 1 bath with a fenced in backyard and it’s on a secluded back dirt road so I could go for plenty of walks and keep my daughter entertained easily. It’s a little small though, and now my SO is saying that he wants me& our daughter to go with him out of state for a month and a half so he can work straight through and save up more money, and when we come back in October sometime find something bigger or “perfect” for us..

my dilemma is I don’t know if we’ll find “perfect” anytime soon, I’ve been looking for forever and this is the first place that’s come up for rent! I need our own place by the time the new baby gets here in December! Also, I’m 21 weeks pregnant and I don’t know if I can miss an appointment next month or if that’s something you just don’t do?

Please, help me!

Do I talk my SO into renting this place for the time being so I don’t have to worry about living with my parents staying in a tiny bedroom with a newborn AND a toddler? Or do I go with my SO out of state and miss a baby appointment so he can save money and find the “perfect” place he thinks exists?
