Is my GF trustworthy?

well what sucks and caused all this is that you have opposite schedules!!! she should want to come home and sleep next to you but you are REALLY SLEEPING.. i'm sure she wants some fun, i'm sure the spark has to die down a bit when you two are not having your fun together. don't track her but tell her that YOU want to hang and have more fun with her. one and/or both of you need a new job or schedule, i know you do this for the baby but you need to find another way as it will destroy your relationship and that will be worse for the baby.
