Spotting months after D&C

Katie
I've been searching the internet, I had 3 regular 28 day cycles since my D&C. We started trying after our 3rd cycle & started spotting brown with tissue the week before my period for a week. Then got my period for five days. This cycle, I started spotting a pinkish red 9dpo which is a week before my period again. I want to cry!!!! I just want to be normal & ttc! My Dr said it's normal to have irregular cycles.
