5 months completed of my postdelivery and I got my first period on 26th Aug. I didn't got my second period yet and there is stomach pain. I give my baby formula milk 2 times in a day rest he is on breastfeeding

A. good morning it is actually very comment to have a regularity in the cycle of periods as long as you are feeding the child that is nothing to worry about when you will stop feeding your baby the periods will become normal
