How do I know when my Birth Control Pill (Yasmin) will be working properly?

I'm 19, just married, and have been on Yasmin (YAZ) Birth Control for exactaly 24 days now. I just took my last pink pill in the packet and will start my sugar pills tomorrow. I've always taken them at exactaly the same time every day, with only one exception. My husband and I had unprotected for the first time tonight confident that the pill is working properly, BUT, I have been looking around in the pill details booklet and online but I cannot seem to find an answer. Are the pills working? Or was I suppose to wait until after my sugar pills and my period? Also, on my 14th day (the day I should have been ovulating) I bleed when I urinated. Is that something to be worried about? I read it was normal for the first 1 to 3 months of Yasmin. Please help. I'm still in college and would like to finish before starting a family... We want to be more ready before having a child... thanks.
