My period is late and Im freaking out Im pregnant even after a negative pregnancy test

(Not looking for any medical advice, just need to get off my chest)

The title says it all, my period is three days late which I know doesnt sound like much but the period is extremely consistent. I have also had really weird symptoms lately like sore nipples, headaches, overly sensitive to certain smells/foods. But the test I took yesterday came back negative, so I should be fine. I just cant shake this feeling something wrong and I dont know if it is anxiety or general stress, but the stress ain't going to help to bring the period any faster.

I know realistically its stress, Im getting ready to finish college, start working full time, and planing on moving out with my boyfriend. But this little voice in my head just keeps saying "nonono we're pregnant, because of course that would happen to us right as were trying to get life plans going" because I know my life and that's how luck tends to work for me.

So anyways, thanks to coming to my tedtalk.
