I've been breastfeeding my little one for 18 months now, my period has been very regular for the last 10 months. But this month I was meant to start my period on the 11th and it's now the 16th and still no bleeding, I used the clear blue digital test this morning which came out negative.
My question is can the breastfeeding have an effect on my menstrual cycle even though its been regular for so long?
