Answer my question please? :)
Take a test. It's possible
You could be, the pill isn't 100% effective as you would know. Take a test with first morning urine and see what it says. The pill can cause brown discharge so it could just be caused by that. If you're not using condoms then you could have an STD which would also cause the brown discharge and could delay your period.
