What's wrong with me 😓

So the condom broke on the 23rd. According to eve, the next day was the beginning of my fertile period. Glow was saying that I still had 3 days or so. Well early this morning (29th) I got really nauseous and threw up. My sister in law was there and trying to tell me that I'm pregnant. I know it's a possibility, but I'm thinking it's too early to see symptoms. It doesn't make sense to me. I'm not sick but I am really tired.
