My breasts are tender and are producing milk for the past 2 months but ive had my period on schedule, can i be pregnant?

Possible tumor: You may have a prolactinoma and should be seen by your obstetrician, though this is outside my specialty.

Not likely: If you are sexually active and not using contraception, it is always possible that you could be pregnant and that must be ruled out first. But if all you have is breast tenderness with discharge, you could have an elevated prolactin level that could be responsible, among other things, and may want to get it evaluated.
