Help? Is it too late?

Crystal

Hi everyone I need so advice. I am 4 weeks postpartum and decided to quit breast feeding because my baby is lil and tongue tied and I also have flat nipples. I became overwhelmed and decided to quit. I have not pumped in 3 days. Is it too late to start back up or did I ruin my shot? My breasts are still hard but not nearly as bad as they were. Any advice appreciated
