There are a lot of consequences of hyperprolactinemia
. In women, a high blood level of prolactin often causes hypo-oestrogenism with anovulatory infertility
and a decrease in menstruation
. In some women, menstruation may disappear altogether (amenorrhoea). In others, menstruation may become irregular or menstrual flow may change (like in your case). Women who are not pregnant or nursing may begin producing breast milk. Some women may experience a loss of libido (interest in sex) and breast pain
, especially when prolactin levels begin to rise for the first time, as the hormone promotes tissue changes in the breast (surprising that you did not mention that in your query). Intercourse may become painful because of vaginal dryness
( do not know if that is your case).
You will need to see a gynobs as soon as possible.
Hope this helps
