Wa'alaykumsalaam wa rahmatullah

Any spottings before the usual period time should be examine in the sense of their smell, color and texture (thickness etc).

Scholars mentioned that if it is accompanied with cramp and pain, then take it as menses, if there is no cramp and pain and it is not during your usual menses time, then take it as istihaadah (false blood) and carry on your Ibaadah until you see blood flow.

Allah knows best
