Should I take placebo pills for vaginal discharge?

I take Vispo contraception, at the end of the previous blister (23.tabl.) I took the antibiotic Ciprinol which I took 4 days. When I finished it, I was on 2 placebo tablets. During the placebo break, bleeding occurred. Now I'm at the end of my current blister and I have brown and bright red vaginal discharge, wondering if I should take placebo tablets normally again, given this vaginal discharge and the fact that several tablets from the current blister had a weakened effect by the antibiotic.
