What type of growth you had on the uterus??
if the pregnancy
test is negative,and you have other symptoms suggestive of pregnancy includy milky discharge,I would advice you to go for blood test
that is Serum. prolactin
level and a sonography
and consult your doctor with the reports. Rise in prolactin levels in the body can lead to milky discharge and also cause a delay in periods. So meet your doctor once with the reports and seek further advice.
