Is this a thing?

I’m 8dpo, got 6 days until AF, and I’m feeling like.. I dunno how to describe it, like something going on on the right side of my pelvis, almost like slightly painful throbbing. Like it hardly hurts but it’s noticeable. I’ve also had (sorry if this is tmi but..) diarrhea both today and yesterday. Lastly, I ordered sushi today for dinner and when I got it, I was repulsed by it because all I could smell was wasabi. What is wrong with me.. I feel like it’s much too early for any type of symptoms if by some luck we conceived, but I just feel weird. Any thoughts?
