Is it normal to worry about your newborn this much?

She is a week old. I can barely sleep, I’m always worried about the way she’s breathing because she will gasp for air sometimes or breathe funny. I get worried to sleep when she sleeps because she spits up so often I don’t want her to choke or roll on her side and suffocate because she can roll on her side already. I literally set alarms for once an hour to check on her . I only really get sleep when my husband is awake watching her. Is this completely not normal? Even for a first time mom with a week old baby?
