Since yesterday I’ve been having mild cramps on and off and light bleeding, that first started with a little pinkish blood with some discharge. I also haven’t been able to fill a panty liner, and it’s hasn’t gotten heavier either it’s been the same. Only there when I wipe a light pinkish blood color no clots at all. Could this be implantation bleeding. I was thinking I could be getting ready to start af but I am also 12 dpo and was 11 when it started.
