Idk if I’m pregnant

I’m spotting very lightly 7-8 days before my period and I’m concerned because that’s never happened. I have felt nauseous once or twice and I’m currently feeling really nauseous and my head is hurting. My boobs feel a bit sore but idk if it’s from me working out or if it’s because my period is in a week. I want to take a pregnancy test but what if it’s too early to take one? And I don’t have to money to buy one either. Ughhh idk what to do!! Should I be worried???

Also the bleeding went away after like 3-4 wipes.
