Breast Pain

Ok, so because of the birth control I used to be on I haven't had a period in about 2 years but I know there is breast tenderness. But my sensitivity is just my nipples. My boyfriend and I are currently not ttc but we had gotten a little lazy the last month and just said what happens happens. My nipples are sensitive to the touch. Like it makes me want to cry. And I'm bloated and 2 days late for my period. But because of the birth control I really don't know my cycle anyway.

Any advice?!?!
