Big Yellow/green Stretchy Boogers Coming out of the Deep End of the Nose After Rhinoplasty? (photo)

Im exactly 2 weeks post op. Ever since 3 days ago, as my sinuses have started to clear up, I have started experiencing these big, gooey in texture, yellow/ green booger looking things comings out of the deep end of my nostrils. Now, they feel very stretchy in nature with streaks of blood in it at times. The color leads me to worry about an infection being present. Note: They're not runny. I have to pick it out by digging pretty deep into the end of my nostrils with a Qtip. Is this normal?
