Ugh help

I’m 7 dpo been checking my bbt and it’s been slowly increasing, I’m gassy and fatigued, my breast are sore and yesterday (6 dpo) I felt this slight throb near my belly button down to my pelvic area and have been feeling morning headaches which I hardly ever feel. Is my brain playing tricks on me or should I wait before AF to test?
