Absolutely call the pediatrician's office and find out if they want to see her. Hardly any of us on here offering our opinions are medical in nature.
Having gone through a serious health situation myself right after the birth of my daughter 2 years ago (cancer) that everyone blew off as postpartum hormones, I'm a BIG advocate for calling and letting the doctor guide you towards a path of peace of mind.
You never know what viruses are going around locally. Both of our kids just had hand-foot and mouth and had most of the symptoms you describe. But, we did call our pediatrician just to make sure they didn't need to be brought in for evaluation.
Good luck.
