Could this be an early sign of pregnancy

Not sure if this could be a sign of pregnancy or if. If it just the start of my period

In the morning for the past 2 morning when I do my 1st morning wee I had some spotting very light when I wipe but none for the rest of the day .. I’ve also experiencing lower back pain for the past 4days I’m not due for for my period until the 30th .. could this be a early sign of pregnancy .. with my other pregnancy I never had any symptoms but the miss period
