Implantation symptoms?!

I am currently 6 dpo and getting light period like cramps and lower back pressure. I also have brown spotting. I’d usually get light cramps but not lower back pressure, I don’t want to get to excited. Just wondering if it could mean anything. Has anyone else had this and had a bfp? I’ve also had some pelvic pain, and a little bit of breast pain. My period is due in 9 days. Any help is appreciated! ❤️ I would post this in general pregnancy but no one answered on there 😢
