Worried about going into labor alone

My husband travels for work during the week and my family lives 5 plus hours away. I started getting random braxton Hicks contractions this weekend. I'm 31 weeks. When is it feasible to ask hubby to stop traveling in case I go into labor? I don't have any complications and expect to get to 40 weeks. I'm just nervous and a bit anxious that I'm going to go into labor and will be all by myself.
