I last had sex two months ago. i took one pill two hours late last week. i have brown discharge. could i be pregnant?

Probably not: sounds like just a bit of breakthrough bleeding. do a home preg test. if negative you are fine.

Pregnancy: I would suspect not although it could happen, but would not be related to taking 1 pill late.

Unlikely: It is most likely a normal physiologic discharge due to hormonal changes. If you are concern or if you missed a period consider a pregnancy test by using early morning first urine.

Possibly but unusual: Being sexually active places you at risk for pregnancy and sexually transmitted diseases. It is unusual to become pregnant because of a single pill taken 2 hours late. See your MD about the discharge and run a rapid pregnancy test.
