Anyone else had or have these

I been feeling weird. Mostly I been smelling blood and I can kinda taste it in my mouth. I don’t have a bloody nose throat or any cut in my throat so that is weird. Also I been having these badddd lower stomach/pelvic area cramps as well as lower back pains. I’m 7-8dpo and feel like I’m on my period but I won’t get that for another 8 days
