Spotting

Hey just looking for some advice , or similar experiences . I’m not due my period for another 8 days and on Saturday i had very light pink which soon turned brown blood when I wiped I still have it 3 days later with mild cramps . My pads arnt filling with blood so looks like spotting , I didn’t have it with my first pregnancy at all so unsure if this is a preg sign or not I will now be 8 DPO unsure if that’s too early . PS preg tests are negative .X
