brown discharge?

Savanna • Hi💗 Just a girl with a lot of questions✌🏼️
So I've been taking Tri-Linyah for 6 months and on week 1 (5 days ago) I missed Friday and Saturdays pill, And I had sex (he pulled out) on Thursday, then I noticed Sunday I missed and then took two Sunday and two Monday. Since yesterday (Monday) I've been having brown bloody discharge. Is this normal I've never missed a pill before!
