New To The Pill - sporting and cramping

So I’m just finishing up my first month on the pill (about to start my placebo week in a couple days), but earlier this week I started having some mild cramping and some faint spotting. Should I be concerned? I did start the pill near the end of my period so I was thinking it’s just my body adjusting to the new cycle, but I figured I’d ask incase it was something to be concerned about.
