We had unprotected sex on my 11th day now im 2 days delayed, tender breast and having white discharge could i be pregnant?

Potentially: Male sperm can survive for as long as 5 days, if not longer, after intercourse. Unprotected intercourse on cycle day 11 can render a woman pregnant, if she ovulates as late as cycle day 16. A delayed period could be an indication for pregnancy. A home urine pregnancy test at the time of the anticipated menses would be positive is a pregnancy is present.
