FTM living alone in third trimester [ON]

Hi. I am a first time mom conceived via IVF and high risk. My husband was laid off since last year and just found a new university professor job in calgary. That means I will be all alone from mid august in my house. My delivery is mid October. I do NOT have any family or close friends who can come live with me. My husband will try fly in home every Thursday to Sunday.

Is it possible to live alone in third trimester? Am I signing up for something impossible? How can I navigate this situation? Any suggestions are appreciated.
