Spotting

Marlena
I'm 5w5d with my second little one 
I don't remember spotting with my first 
But yesterday I noticed a discharge of a brownish color and today again but the last time I went to the bathroom and wiped it had small amount of bright red in it 
I have had the normal cramping non of concern but the spotting bothers me some because I don't remember this with my first I have an appt with my OB next Wednesday do I need to be in major concern or is this just implantation bleeding the bright red has me more concerned
