Is it too early to test?

Hi ladies. I'm 4 days DPO and the past two days I've been super irritated and emotional...I've had some acid reflux but I definitely feel like it's way too early for these symptoms to be pregnancy signs..I'm supposed to get my AF in 10 days..I just so badly want to take a test and for it to be positive but I don't wana sike myself out. We've been trying for two months but this month, i used ovulation tests and pre seed to hopefully help.
