Is it just spotting?

Ivanna

So my period isn’t due for another week or so (and there’s no chance I’m pregnant just as an FYI lol ) but recently I’ve woken up to stained underwear from what I assumed was spotting.

I went from never spotting to every once in aaa while and I’m just wondering what’s the cause? I recently lost some weight and I’m on a new diet. Could that be affecting it? Thank you :))
