9 dpo and symptoms!

sometimes i feel like im making symptoms up in my head...like its too soon for symptoms is it?? ive had to go pee in the middle of the night the last two nights and i have NEVER had to before. I had a brownish cm 7dpo...minor minor cramping almost not noticeable unless i was paying cloae attention same day as cm color. Is it too early? AF supposed to start in 7 days.
