Sticky Implantation?

Lauren
Does everyone feel implantation cramps without getting pregnant? I don't know that I have felt them like this previously. We have been TTC for a year so I can't say I am new to this. It's been a dull annoying pain most of the day. Uncomfortable whether standing or sitting. I am feeling really tired no matter how much I sleep, I track my sleep with an UP24 band so I have a good idea.  I am CD 19, DPO 7, next AF on 10/27. I just don't remember feeling the cramps this much at this point of the month previously.
Does the crampyness mean good things or am I just too hopeful? Does this mean I will get a BFP soon or have others felt the cramps without it sticking? Thanks in advance.
