Birth Control Pill Scare

[monikaka]

I'm on my first month of Birth Control. I am currently taking Yazmin 21 pack.
When am I supposed to get my period?
I started to get it the day of my LAST pill before I took the last pill but I only wiped blood ONCE, after taking pill number 21, It's been a lot of brown discharge.

Is it normal to miss your period even when you are on Birth Control?
I lost pill number 17, but didn't have sex that day.
I took pill number 18 and had sex about 10 hours later and took pill number 19 at the same time as the day before(1pm) and had sex afterwards.

Does losing a pill interfere with the WHOLE month cycle? Do they each have their day's dosage to protect you THAT day or is it a little bit each day to where it complete's a whole month's need of taking that pill to be protected on ANY day of that cycle?

Or was I protected since I took the day's pill and had sex only on the day when I did take the pill I was supposed to take. Then, I had sex the day afterward but I took that day's pill as well. I used a condom on both occasions, and he never came inside of me. He pulled out right before just to be EXTRA careful. He did, however, insert his penis like 3 or 4 times before we actually engaged on sex but never came. I have heard of pre-*** and it being enough to get you pregnant, but I took my birth control pill so was I protected against that JUST IN CASE?

Well, not to worry you, but my 5 year old came about when I was taking yasmin birthcontrol.  
Birth control pills are not 100% proof against pregnancy.  Actually one fact many women don't realize is the 99% effective number for birth control is when the woman isn't at all over weight.  If you are over weight a bit the effective rate drops a bit.  
You should get your period on the sugar pill days of your packet.
You need to make sure you take your birth control at the same time everyday if you are using it to prevent pregnancy.  
Antibiotics, and cortizone mess up the effects of the birth control
Usually missing one pill will not cause any problems as long as you have made sure it is only one pill you missed.  I can't stress to you enough though to make sure you take your pills at the same time each and every day.  
You might take a pregnancy test just to make sure your not pregnant if in fact you did miss your period.
