I am taking yaz flex and took my last pill on Tuesday for a 4 day break. I didn't start bleeding until Friday night/Saturday morning. Today is Sunday and I'm due to start taking my pill again tonight. How long will I generally bleed for? This is my first 4 month cycle and I didn't have any breakthrough bleeding since start, just a couple of days of light spotting, not even enough for a tampon. I'm hoping that I will stop bleeding by Thursday. Do you think this is possible?
