Sorry if this is all a bit confusing, I'm not an experienced poster! 
My DD is now 13 months old and still no period! Vaginal delivery, very quick and unproblematic. She was EBF until 7 months and I still feed her at night (3 times between 7pm and 7am). I don't bf during the day and haven't done for a couple of months.
With my first child (DS) I didn't get a period after giving birth to him, and instead got pregnant with DD when DS was 11 months. I must have gotten pregnant at my first ovulation?
Has anybody else waited this long to get their periods back?? Is my (very small amount of) breastfeeding the reason?
