should i set an alarm or adjust my sleep to my baby

im 38 weeks pregnant with my first, i dont work, im finished with school so i will be at home with my baby all the time. her crib is in my room (she will be sleeping in my room) so due to that and the fact that i dont have to be up for any reason but her, should i be setting an alarm or sticking to a schedule or wait to adjust mine to fit hers and sleep when she does and decide when to do other activities like laundry, cleaning ect... after im awake? my biggest fear would be having an alarm set and having it wake her up. advice on what to do?
