am i pregnant or what? i really need some input

it’s probably pretty impossible that i’m pregnant but with unprotected sex anything can happen.

i’ve had all these symptoms, nausea, terrible headaches, breast pain (more like nipples) cramping a week before my period was due ( i don’t cramp until the day of), very emotional, and big appetite but not really being able to eat.

2 days before my period i had what i thought was implantation bleeding. my pads and liners only had spots on pink/brown blood on them, but when i wiped it was more than spots and it was a very very light red/pink color. it ended the next day which was yesterday. it’s confusing because my regular cycles don’t look that color, and i at least have way more blood on the pad.

i tested a week ago that could’ve been too early, but i also tested last night and about 30 minutes ago. all negative. should i wait and test again or give it up?
