Implantation Bleeding??

My period isn’t due for another week. I started getting a light pink and brown discharge when wiping throughout the day yesterday. This morning I woke up, had a few drops of red blood on my toilet paper, but it ended up being watery, light pink/brown again throughout the day. According to this app, I’m 8dpo today.

I’ve also been having mild cramps these past couple of days, and mood swings… also urinating more so I’m hoping it’s not a UTI.

Note** this picture doesn’t do it justice what I’ve been experiencing these past two days. It’s minimal and very light in this photo.

Is it too early to test??
