Donno feel weird, might be pregnant?

Soooooo I usually have very very punctual periods like clockwork. The last one was between the 30th of Aug till the 5-6th Sept. ok I’m in a relationship so we went on a holiday great exactly when my ovulation was estimated had the usual ovulation symptoms + a little extra at the end of the holiday crazy allergy sneezing I’ve never had in my life. Came home “period” came earlier with 2 days. Came with pink spotting. Cramps but not the usual spots - lower belly left side It was very light compared to my usual period when I fill up at least 4-5 tampons/day. Lasted for 3-4 days. Since coming home or even earlier: Breast sensitivity, Weird food cravings Wanna eat nonstop Hot flushes Sleeping on my stomach!!! For the 1st time in my life never ever happened to me Itchy skin Nausea Smell sensitivity Bloating Moodiness tantrums etc Headaches Ah and sleepiness fatigue

Besides negative test… why? 🤣 I’ll do the test again on the 3rd-4th cause according to some of my calculations that could be the date? Help help help…
