Help?

I'm 9dpo, yesterday and tonight I've felt pinching in my lower left abdomen. It's out of my norm because I don't cramp until the day before AF is due and that's if I cramp at all. I know some are skeptical about implantation cramps but could this be it? This month has just been weird period. Normally I'm starting to have pms symptoms and I have absolutely nothing. Thanks ladies. ☺️
