Ftm baby sick? please help

My daughter is almost 7 weeks old. She's had a stuffy Nose and my dad said she sounded congested yesterday's. She's ebf if that matters. Her temp is 99.2. BUT my child NEVER cried and she's been awful tonight. Constantly screaming and crying. I've tried skin to skin and constant cuddles and rocking. She just acts different and like something wrong. Any help
