What is going on!?

So my period was due on Wednesday. I am SUPER regular. But It never came. pregnancy test was negative. I did have some period like symptoms (bloating and slight cramping) on Thursday but aunt flow still never made her appearance so I took another test. Negative again. Took one Friday, negative again. I’m no longer bloated or feeling any cramps. I don’t feel like I’m getting my period at all. My question is, would it still be possible I’m pregnant? Maybe Thursday was implantation? Or should I of gotten a positive test by now if I really was pregnant and now my body is just playing tricks on me to give me anxiety lol😩 has this happened to anyone where they tested positive days after “missed period”?
