please help

im pretty sure i was implant bleeding the other day. it was pinkish brown and i had cramps but they werent like period cramps and i was supposed to be on my period by now but im not and im not sure if the bleeding i had was like a hoax period or something? it wasnt even 2 days (i started late one night and ended the next day) it was very very light. im not sure when the best time to test is? should i do it asap? or should i wait until my period is completely missed?
