welcome to health care magic
Normal serum levels of prolactin
are 2-25 ng/ml..But that small increment won't cause irregular periods
Irregular periods may be because of other abnormalities like thyroid
,,may be fibroid in the uterus..
you have to check thyroid profile also...
if the thyroid profile is also normal then consult gynecologist and she will prescribe the dopamine agonist
tab..and soon your prolactin levels return to normal..
For further suggestions consult gynecologist..
