Not sure what to do

Tracy • My husband and I are expecting another child. We are having a girl! Her name: Kennedy An! My older kids r happy! 😀🍼🎀
I am one week late from getting AF and my tummy is full of butterflies and I've been nauscious. Also my anxiety got really high and that hasn't happened well since I had my last child 5 years ago. Pee tests don't usually work for me. Should I try a pee test first and see? Or just get a blood test? Also I've been hungry a lot and dizzy spells. 
Any suggestions?
