Spotting?

I got what I thought was my period earlier in the afternoon, shortly before going to my boyfriends house for dinner. I checked on my tampon after dinner because I had not bled through it and onto my pad, which I found strange because usually I bleed heavier during my first day, and There was only a little bit of blood on it

According to <a href="https://play.google.com/store/apps/details?id=com.glow.android.eve">Eve</a> my period is supposed to arrive in 3 days. I am not (and have never been) on any form of birth control. My cycle is regular and I rarely spot, if ever.

Should I be concerned? Or is it just my jiggly bits being weird as they usually do 🤷‍♀️
