Hi, I am 27 years old. I delivered my first baby on 13th Jan 08 virginal after that bleeding continued for 62days. I am breast feeding. 1st time I had sex after my delivery on 15th April and still I have not got my periods... Is everything OK with my health and is this normal??

With breastfeeding it can take a up to a year or more before you get your period. It is normal. That does not mean you can not get pregnant at some point though.
I breastfed my first and no period for a little over a year (14 months) then found out I was around one month pregnant.
