I'm 31 years old and I have a 8month old baby. The first 3 months I breastfed so I didn't get my period until 4 months after giving birth. Ever since then my menstrual cycle has been between 30-35 days. Usually 3-4 days late today I'm on day 45 of my cycle and no period yet. Could this be normal? I am sexaully active but we use condoms as protection.
