Is this implantation bleeding or start of period

I had small amount of light pink blood on my toilet paper last night before bed so I put a tampon in and this is what it looked like when I woke up this morning. I wiped it with toilet paper to get a bet look and it was a brown color. I’ve never had this happen before. I know it’s hard to tell in the pic but it’s definitely brown and not red
