I m 36 years. My period started after 1.5 years of delivery of baby(c-section). I have 2 kids. Both c sections. Second baby delivered on 16 Aug 2016.period started on April 18. I m breastfeeding my baby. First 3 month period was normal - 28 days cycle n on time. But July month period I didn't got on time. It delayed my 10 days. Also this time period is extremely light. Sometimes I see blood on pad. I can't understand suddenly why period delayed n it is so light. Like negligible. What to do?? Pregnancy test is negative as per blood test asked by Gyno doctor. Please let me know why it happened this time. And what I should do.
