I do not feel that your symptoms are directly related to smoking
. These symptoms are most likely due to some kind of hormonal
abnormality which could have been a complication of delivery. I would have liked to know if you bled a lot during the delivery and whether you have had any problems in lactation
or not. Please consult your gynaecologist/obstetrician regarding these problems so that a hormonal assessment can be done. Please also consider quitting smoking, as whatever be the reason for your symptoms, smoking can only worsen it.
