Spotting?

💙Shadoe✨ • Just conceived our rainbow baby:) M/C in March 14 & chemical November 14... Going to marry the man of my dreams<3 After 14 months of trying finally got our BFP 8/7/15! Praying for a sticky baby🚼
So my period started 3 days early... I have just been barely spotting tho with very minimal other period symptoms.. Could this be a sign of something?
