Should i wait 1 week after missed period to take a test?

I am here in japan, and the prengnacy tests here says 1 week after missed period. Been TTC for a year. Last month i bought an opk and i am very anxious now about taking a test. So far, sore breasts and fatigue (i guess are my symptoms. No Implantation bleeding either. Been 3 days late. 🥲 should i tAke a test tomorrow or wait until friday.
