I had some bleeding at about 6 weeks PP with my 2nd ds. I called the nurse because it concerned me. She said it was just AF and not to worry about it. I knew she was wrong. There was no reason for my AF to be back so soon. I was exclusively breastfeeding on demand, co-sleeping, holding or carrying baby in a sling all the time. I couldn't even put him down to nap. He'd wake up within 20 minutes, so I had to lay down with him for all naps. After that bleeding, I didn't have anything else until about 6 months PP. Then again nothing until around 11 months PP. At that time I started to have regular bleeding so I started charting again. It wasn't AF because I didn't ovulate again until about 15 months PP. So, don't freak out yet. It may just be what the PP said, a sign that you are overdoing it.
