Spotting? Implantation?

Lauren • 34 expecting baby #4! 💙👶🏻💙👶🏻💙👶🏻💗👶🏻
Yesterday I noticed a tiny, TINY bit of blood when I wiped and I mean tiny, like 3 small dots. Today my breasts are a little swollen and tender. I'm still 12 days from my period (according to glow, but I'm constantly inconsistent) could that have been implantation bleeding? Could I be pregnant? This is only my 1st month TTC #1 I've just never done this before and know nothing! Help! Lol
