Pregnant?

Yesterday I started feeling sick at work so I left early. I was nauseous and achy. I was running a low fever last night and because my stomach I wasn’t able to fall asleep until 11. Now I’m awake at 5am for the same thing. My stomach feels really bloated and nauseous but I can tell I don’t have any fever anymore. My period is suppose to be in 4 days and I never have bad period symptoms. Is it too early to think I could be pregnant?

Me and my bf live together and never use protection.
