Confused πŸ˜“πŸ˜“πŸ˜“

Hey, not sure if anyone could shed some light on this for me! Driving me mad! πŸ˜•
Started my period on the 12th of July -14th (usual length) I am TTC but last night I noticed a bit of blood... Not much like a period, but dischargy. Any ideas what this could be?Β 
Thanks in advance everyone 😘
