Help!?

My period (usually) I use that term lightly... comes between the 5th-7th it's now the 11th and I'm curious could it possibly be what I'm thinking?? I don't want to jump to conclusions or buy a test if I'm just abnormally late. Should I wait it out another couple days? Or just buy a test? I'm already a mommy of 1 so I thought I'd know like I did the first time but 🤷🏽‍♀️

Oh and symptoms

Nausea (sometimes)

Exhaustion

Light headed ( everything will go black for 2-3 seconds)

Bloated (I assumed because of possible period coming)
