Period or implantation bleeding?

Girl Mama 💕

I started (or so I thought) my period last night. It was very light pink and only when I wiped. I put on a panty liner anyways just incase. But it only lasted until this morning and still only when I wiped and now it has stopped. But my boobs have been SO SUPER SORE for the last couple days now and now I’m not so sure that’s it’s my period. What do you all think?
