WHAT ARE THE CHANCES ‼️⁉️

Sheila
So my boyfriend & I did the deed December 27th; however, I never noticed until afterwards my ovulation date was December 31st (five days before ovulation) now when I eat certain foods, an hour later I'm hungry, nauseous, also a little hot. Oh yeah every time I drank coffee to which I love all of sudden I get cramps. Stop drinking coffee no cramping. Any advice what's the chance could I be pregnant ‼️⁉️😇😬😊
