AF no show

So for about 6 months now I had transition to. Vegan plant based lifestyle. And for the first time ever my pds were every month. I have always been irregular. This month I've been drinking more sugary drinks (cocktails) then ever, been bingeing more, I dislike pickles but yet I want them; all this in the last 2wks. So, glow has said I'll start this day and that day, I didn't- so I deleted, going on for the last 2 wks. Then I was supposed to start today- no AF. Deleted today. I don't have any symptoms if I were to b pregnant. Well, with my first pregnancy I never didn't till 2nd tri. Then my mind keeps racing could I just be drinking more cocktails and eating more processed foods lately? So tomorrow I am going to take a test.
