Kind of nervous

So I'm not really trying to get pregnant but wouldn't be upset if I was either. I have been having sore breast for like two days now and it hurts really really bad, and also mild cramping. I usually get those a week before my period but yesterday I started to spot light pink blood tmi and was certain it was my period. But it was very light. I woke up today and I had nothing. Idk if I should test or just wait today out to see if it was really af. Im confused idk what to do.
