SERIOUS QUESTION

okay so im about 6 dpo, and i don’t feel any symptoms at all, is there still a chance for pregnancy? i’ve had no cramping (that i know of) (i haven’t paid much attention) and no spotting no nothing. i had sex all throughout my fertile week! is there still a chance??? and if there is, can someone fill me in on information regarding conceiving because if there is still a chance (not to get pregnant but to be pregnant) i’d like to know. like, when does implantation happen? and when will symptoms show?
