I stop talking my birth control , a week or two weeks later I decided to have sex , my period had went off 5 days before. Almost a month later my period came on for two days , a week later I had brown discharge for about a week. What could this possibly mean ?

It can be a sign of pregnancy, a sign the body is adjusting to no pills, a sign of an infection.
The list could go on.

Have you tried a pregnancy test, first thing in the morning?
