What is safer?

My husband is currently away for work. Am 32 weeks and have been having pelvic pains since 18th weeks. I go to my parent's place most of the time but of late, am just so tired. It is so hard climbing the stairs. They live in an apartment on the 4th floor without an elevator. I really want to go to my home because these stairs are killing me and not helping with the pain I already have.

My husband thinks I shouldn't be at my place alone so I should wait to go there just in case labour comes on early. He thinks it is safer to have someone around. And he tells me I should think of the people that love me, how worried they would be. And it is annoying me because I keep telling him how much pain am in but I should stay here so other people don't worry. Mom promised to come see me some times. And even sleep over. Also the emergency call for ambulance is really easy and I feel they would get there in time in case of an emergency. My pregnancy has been good, have no health problems aside the normal pregnancy symptoms. I just am so tired of these stairs and the pain. Am I being unrealistic to want to sleep in my own place that is on 1. Floor and has a elevator? What should I do?
