could I be pregnant ?

i’m inloveeeee with pizza, it’s my favorite food i could always eat it no matter what. but we got it 2 days ago and the smell made me want to throw up so bad!!! so I didn’t eat it. then the next morning I brought it for lunch to work and I tried eating it but again the smell and taste made me want to throw up. That never happens to me for anything. And me and my boyfriend are trying to have a baby. I got off birth control a little under a month ago and we had sex on my ovulation day and of course he didn’t pull out, but it’s too soon to test to get the right answer. But I know my body and I am always down for pizza and now i can’t even deal with the smell !!! did anyone have this when they first got pregnant??!??😁
