puked last night on first day of missed period...

I'm too scared to take pregnancy test bc some cycles I'm 27 days and sometimes they are 28 (which means maybe I'd just get my period tomorrow). I ALWAYS jump to take a test early and it's always negative and many woman who check early get a false negative and it's been 10 months of trying so, I just rather wait it out. But why did I puke?! I had creamed spinach at a steakhouse and other people ate it too at my table and I'm the only one who puked.....praying I'm pregnant...anyone with similar stories who ended up pregnant, please share!!! I felt fine after i puked too...hmmmmmmmmm 🙏😩🙏
