Thank you for your query.
Firstly, you have nowhere mentioned your last menstrual period, so the question of pregnancy
is a tad difficult to answer without that information.
Breast tenderness and vaginal burning or discharge are not reliable signs of pregnancy.
It could be due to a separate breast condition and a separate vaginal issue.
It could be due to birth control or any medications you have taken.
The vaginal infection
, if you are having yeast infection symptoms, can be attributed to vaginal yeast infection.
The breasts definitely need to be examined to comment upon.
ANd you should check with a gynecologist to confirm pregnancy, or if periods are overdue, take a simple pregnancy test.
