Just a question if someone could help me out

So I had gotten my birth control bar removed (nexplanon) on the 16th and got my period 2 days after & only lasted 3 days but lately i have been feeling weird like ive been light headed very irritable actually very emotional period & nauseous on & off throughout the day I have a first response 6 days earlier pregnancy test but it says to take it 6 days before your period& my period isnt due for another 2/3 weeks should i take it anyway or save it til it says?
