Is this an early period sign?

Hi guys! I’m currently on cycle day 34. My periods are irregular and usually come anywhere between 40-50 days, however sometimes are as early as 28/30 so I really can’t give an accurate representation of where I am in my cycle lol. But today and yesterday I noticed some light pink spotting along with some cramps. I put a tampon in before I went out just in case and this was on the tampon. Is this likely just an indicator that my period will start in a few days or something else? I’ve not had unprotected sex since the start of my cycle, and always use condoms. Thanks for your help!
