travail advice

Sarah • Single mom of 4 beautiful babies. All my babies have autism and seizures. Love them so very much
Ok so at Christmas time my husband wants to drive to Arizona from Sacramento CA for 2 weeks first I will have a 13 month old and I will be 32 weeks pregnant when we go and 34 on the way back. My son tried coming early 4 times. Starting at 28 weeks then at 30 then 32, and 35 weeks he was born at 38 weeks. What do you think my chances are of going into preterm labor?  Should I just stay home?
