Testing too early?? Helppp

Deziray

Hey guys! Hoping so badly to be pregnant! I had spotting 4 days before my period was suppose to come! Lasted 2 days of on and off light bleeding. (Think it was implantation bleeding) and now my period didn’t come today. But the pregnancy test said negative when I tried on Wednesday.. could I have been testing too early?! When should I retest again?
