Pregnancy symptoms

I took a pregnancy at 8/9dpo both negative I’ve been dealing with boob pain which I’ve only ever felt when pregnant, this app usually is off by 4 days on my period, usually get my period 4 days before it says I will I’m 3 days before my period could I be pregnant? Had sex quite often around ovulation and on ovulation but used pull out method (I know not effective). I’m 11dpo now should I text again or wait till my period?
