Qlaira Missed pill bleeding

Hi guys, I'm on my second pack of Qlaira after switching over from Yaz (with a 2 month gap in between brands) On day 16, I missed a pill and the following day started bleeding and having full period symptoms. This has now been going on for 3 days. Is this normal? As far as I believe I should only be getting my period during those two placebo days at the end of my pack? Any advice is appreciated!
