How To Stop Menstrual Bleeding And Cramping?

Hello, I'm 23 and missed two Yaz pills in a row (no 13 & 14), made up for them as per the instructions and continued taking them regularly. However, I've been experiencing light to moderate bleeding and cramping for 7 days now. Anything I can do to make it stop (I'm on a business trip this coming week)? Any indication of how long it will last? Thanks!
