10 dpo implantation bleeding?

Katie

I am currently 10 dpo and woke up this morning with this light brownish pink spotting and tender breasts. I am testing negative on a pregnancy test, but I am confused because I am someone who typically has very regular, 29-day cycles and never start early. I’m a little worried because I have had two miscarriages in the past year, so I’m hoping this is implantation but hope it isn’t a bad sign I’m bleeding. Is it odd that I am having t this kind of bleeding with negative test? Has this happened to anyone and then they got a BFP?
