Possibly pregnant?

Hey❤️ I’m kind of stuck in a situation, I wasn’t intimate this month on my fertile days. Going off the app it said I was fertile the 12th through the 18th and I ovulated on the 17th. I was intimate on the 22nd and 23rd. My period was supposed to start the 31st and I still haven’t started yet. I took a digital test today and it showed negative. Is there a possibility I’m pregnant and it’s just to early to tell or am I just late? My period is consistent. I’ve been really sensitive to certain smells, I’ve been urinating more frequently, and I’ve stayed soooo tired.
