Weird boob question


So today I noticed something out of the ordinary that I have never seen before. I had an itch on my nipple and when I went to scratch it inside my bra I noticed what looked like a few drops of blood on my bra cup right where my niple sits. First time mom so this is nothing I have ever experienced with my body before and i have already reach out to my ob to see what she has to saw. I curious if any other moms have had this happen. I had not marks indicating that I may have scratch too hard so I am a little baffled.
