6dpo could I be getting a positive soon or just af

4-5 dpo and been cramping all day. Yesterday I was cramping off and on. I've been cramping none stop and period is next week so it can't be that. I've been having headaches all day, back pain, and back and forth to the bathroom. today I am 6 dpo, I keep going back and forth the the bathroom tmi but doing the number 2 a lot often the usual. little (sore) more of achy lower stomach. Could this be a sign of BFP?
