HELP!! Brown period on birth control??

Dierdra

I’m currently taking Vienva birth control and I had sex with my boyfriend, he wore a condom as well, on October 10th. A few days later I started having brown discharge and even through my placebo pills at the end of the pill pack I still had brown blood. Is it normal to have brown periods while on birth control?

P.s. I’ve been super stressed lately and I haven’t been eating very much because I have lost my appetite.
