Earliest you KNEW!!

So I am 4-5 dpo and I swear I know I'm pregnant (not 100% but pretty sure). I feel different than ever before. I am also aware that I had two follicles available (because I got an <a href="https://glowing.com/glow-fertility-program">IUI</a>). Cramping near my hip bone that has lasted about 12 hours. I'm not anywhere close to my period unless it's supposed to come early but I just feel different. I know I've got several days before I can test especially because I got a trigger shot but anyone else been there?
