Prevented period - brown discharge

hi im currently on rigevidon contraception pill which normally you take on for 3 weeks and off for 1 but i took my last pill packets back to back to prevent my period as i was going on holiday. ive been experiencing brown discharge for the full month basically! has anyone else ever experience this or can offer me guidance?

That can happen if you carry on taking your pill without a break. It will go back to normal next month if you take it normally again.
