Hoping someone has experienced this before

Im very regular with my cycles and i never get any PMS symptoms til the first day i actually see AF. I'm 9 dpo but the past couple of days I have been very nauseated, light cramping,extra sensitivity in my breasts ( not sore feeling)and I cant stand the smell of certain foods/smells(never bothered me before) it makes me gag. My temperature is also staying around 99.7 but I'm not sick though. I hate testing early just to be negative anyways. Just curious if anyone else has experienced this. I'm gonna wait til missed period to test. I'm also not stressed or anything like that. I've actually gotten a lot better with staying positive and letting negative things go. Thanks for reading and giving me feedback!
