is something wrong with me?...

according to eve and other resources, on day 3 of my period I should be feeling happy and sociable. Instead I’m in a really bad place. The lowest low I’ve had in a long time. I was pretty happy a couple days ago but I’ve had trouble sleeping and my mood is deteriorating. is this a sign that I need to mention to my mom/doctor? I’m a teenager so I know it just might be “weird hormone fluctuations”. I kinda just need someone to reassure me I’m perfectly normal.
