What’s my possibility of being pregnant? Tmi

So I’m on the pill, and last had sex about a month ago. Didn’t miss a pill(took one pretty late though) We did it twice within a few days and he didn’t pull out either time. For the past week or so I’ve been extremely bloated(extremely). Been extremely tired. And CONSTANTLY hungry. It’s like if I don’t eat every few hours or so I start feeling nauseous and sick. I also have a slight increase in smell. Do you think I could be pregnant? Has anyone had something similar happen? I plan on testing just to make sure but I just wanted y’alls opinions.
