9DPO - Pregnant?

Hi ladies, just want some advice - I’m 9DPO, since Thursday I’ve been extremely touchy & hormonal. My partner breathes and I want to kill him, I’m normally hormonal on my period but this is a whole other level. I didn’t have breakfast as normal this morning so I’ve been starving. Had lunch at 12, but it just made me want to heave! I don’t know if it’s too early to experience anything if I’m pregnant .... advice?
