Baby acting different

My daughter is 7 weeks old and she seems really irritable today and not wanting to cuddle. (No fever, no constipation or gas) she usually likes to be held and shes now at the point were she can make eye contact and smile.. well today she seems content in her swing and will not make eye contact with me.... almost like she doesn't want to be held or by me. I've tried to engage her but she just seems like she wants to be alone or something?!? When I try to hold her she gets really squirmy and fusses.

Shes sitting in her swing looking at her mobile now content.

Is this normal???? I am I probably could paranoid but she usually loves to be held and lay with me.

Any thoughts?
