I had my baby almost 9 months what are some reasons that my period never came back? Should I be worried

Breast feeding? . Breast feeding can delay the return of your normal cycle.
Maybe. It can take up to 6 months for your periods to resume after having a baby, so you should be having periods by now - unless you are breast feeding. Half of the women who breast feed will not ovulate and will not have periods. If you are not breast feeding, it is time to see your doctor.
