Hi, I really need some advice on what to expect. I took 4 yaz pills, each day starting from the first day of my period. I then stopped after four pills coz I decided I did not want to take them anymore and now I period is 5 days late. When should I expect my period? Usually I have a 28 day cycle like clockwork. Also, the last time I had my period and took the 4 yaz pills, my period lasted 10 days. I'm going abroad in 2 days time and I'm really anxious. Thanks P.S. definitely not pregnant! I just really want my period to be back as normal.
