Hi dr my c section was on 14 March after thar I got my periods for 45 days on 29 May my period started again with bright red blood and I'm exclusively breast feeding????

It’s absolutely normal to have periods on time also with bright discharge even if u r breastfeeding and had c section. I have similar experience so relax. Happy motherhood

for 45 days it was not periods it was left over blood after delivery and body was cleaning itself

That blood is called lochia . That was the blood which helped your baby grow.
