Moving into a house with roaches while pregnant

I’m currently 22 weeks pregnant. I am currently living with my mom until I get completely moved into a mobile home my fiancé and I are renting. The landlord did tell us there were roaches and he has bombed the house a few times but there are still some that we keep seeing that are alive. I’m not even sure why the landlord would let us move in before knowing for sure that they are all gone. The landlord hasn’t hired a professional and won’t be back until about a month so my fiancé hired someone himself to come out next Thursday to come out and treat the house. I’m supposed to move in tomorrow but I’m so nervous. I’m pregnant and really don’t want roaches crawling in my ears or getting into my stuff and causing issues for my unborn child and I. What should I do? My fiancé wants me moved in asap but I’m so scared of the roaches getting me sick.
