Hello dear, please do not be worry so much about it!!!
you are mentioning all the pregnacy sympthoms at the same time!!! give your self some time, you are only one day late, wait till next week to worry, some times periods will be less than other times, the cramping could be due to changes of weather, a little cooler and damp...all your symthoms are typical of pregnacy but if the test came negative, just relax a little bit, for piece of mind just wait 2 more days and take the test again, make sure you have not eat in 8 hours,
the stomach sickness could be due to worring so much,
some times anciety messes up our body too. Perhaps you have abeen going to start soon, my only sugestion to you is to take another test early in the morning eather in the next 2 days, the test are very accured and if this time came negative most likle you are not pregnat!!!
Please keep in touch! let me know in the next 2 days!!! I'll be praying that it is what God wants for you at this time in your life.
