Spotting ???

Laura

My cycle always comes in time it’s always on the 1st of the month it’s never failed me once. For some reason I’ve been spotting very light pink for 2 days now and I’m not sure why, also having a clear discharge , but looks sorta like mucus. I guess my question is this normal or is there a problem? I’m not having any symptoms besides Breast tenderness. Can someone let me know if this is normal even if I’ve never had this issue before. Could I be pregnant?
