8dpo and headaches from hell

I’m 8dpo and yesterday I had cramping but it’s nowhere near my period (period due in eight days) I feel like crap and I’ve been feeling moody and wanting to punch some people in the face lately. Headaches are outrageous (never really got headaches before) and I just feel like crap altogether. Yesterday I felt nauseous and dry heaved but today nothing fr. Just playing the waiting game... I’m also waiting for my Wondfo’s to come in so that won’t be til 10dpo (ordered them yesterday off Prime) I BD’d on ovulation day..... so yeah.....
