Am I crazy!??

App says I ovulated on the 30th, we had unprotected sex on the 31st. I swear with everything in me I have just felt different. A little nausea, few mild cramps, my V felt a little “pained” or different this morning . Coffee tastes weird , indigestion, and just overall feeling very different according to the app I would only be 7dpo. Could I be pregnant!!???
