8dpo/9do symptoms ! Should I test ?

Today (10:00)pm I am 8dpo . 6 dpo I had slight cramping as if they were only uncomfortable when I acknowledged them . 7 dpo was a hard day I couldn’t keep anything down and my right boob kept getting what some call zingers ! I personally don’t get pms symptoms getting cramps this early didn’t cross my mind however my boobs are killing me and I’m unfamiliar with this feeling , 7dpo my lower back was killing me even laying down didn’t help again I don’t experience pms symptoms so this is unfamiliar as well , today 8dpo I’ve been having this headache on and off for the past two days and I threw up again as well . My boobs are again aching! Do you guys think this might be a positive note if so when should I test !?
