TMI...concerned

So I gave birth 2 months ago. No complications. I had a 2nd degree tear. Been back to the Dr she said its all looking good. Ever since a couple weeks ago when having a bowel movement it hurts. Not encrustating! But then when I wipe there is blood. Tonight, I looked in a mirror at my butthole and noticed that there is a gash/cut looking spot and its blood red. I pushed on it to see if blood was present, but nothing went onto my finger. I'm not in pain other than when going poop sometimes worse than others. I've looked up roids and it looks nothing like them. It's almost like they didn't stitch far enough back and it's open a little yet? I don't know. Any ideas!!
