pregnant?

I believe I ovulated on 8/20 ( had egg white strechy cm). on 8/27 my nipples became really sensitive to touch. here we are 9/1 and nipples still hurt to touch and have since the 20th, also the past few days have started getting heartburn, emotional, bloated and gassy, fatigue, mild lower backaches and hot flashes. have mild headaches that come and go but for some reason I still don't believe I could be pregnant. I know some of my symptoms are the same as pms but I'm still 6 days away from my period and never had symptoms start this early or nipple pains like this. it's usually my whole breast that are sore with pms. any thoughts? plan on testing today or tomorrow!!
