I have been spotting for 5 days and now i am 3 days late on my period. i have been having headache, really bad back aches, nausea and some tenderness of my breast but i haven’t taken a test yet bc i don’t want to get my hopes up but idk what to do.

i was supposed to start my period on the 6th of feb but since yesterday i have not had any spotting or anything. the spotting has been very light just for a panty liner or when i wiped. i am like 17 dpo. should i take a test or should i wait?
