pregnant?? or not pregnant?

okay. so exactly 16 days ago (or two weeks) i had unprotected sex with no birth control (i know seems pretty bad). and now just a couple days ago to now i’ve started to get tingly boobs, headaches, dizziness, i’ve started to smell weird scents out of no where! but today, i took a pregnancy test and it came out negative. thing is, i know my body like the back of my hand... it’s never done these things before, EVER. should i wait to take the second test or what?
