symptoms in very early pregnancy normal?


So my hubby and I just found out we are pregnant. It’s extremely early on. 3.5 weeks. Haven’t even missed period yet (technical due date tomorrow). But I took seven early pregnancy tests all positive including digital. Well we are over the moon. But I’m experiencing symptoms already and it’s making me nervous. I have extremely sore breast’s, very tired my eyes are heavy all day, and back aches. Did anyone else experience symptoms this early?
