Will I turnout to be pregnant?

Okay so according to my period tracker I had my period on May, 11th - 16. I was fertile from May 15 - 21st and I ovulated on the 20th. I had unprotected sex the morning of today (the 23rd) I know it's a little soon but I'm always cautious when I have unprotected sex and I would like to take the opinions of you guys too see if theres a chance I might become pregnant even though I didn't have sex when I was ovulating or on my fertile days. I'm also planning on buying plan B. Please nothing rude I'm just curious and uneducated lol.
