No Period on Birthcontrol??

Ok, so I've been taking my Birthcontrol around 9pm every night, sometimes at 9:30. Sometimes at 10.

But within the same time frame...Ive been taking my Birthcontrol while skipping my placebo pills as well.. just for fun. Plus, I never had peace of mind with the placebo pills.

My last cycle lasted FIFTEEN DAYS LONG (ugh)

But it was very very light, the cycle before that one was 9 days long. It just seems my period has slowed down so much that I may not get hardly a period anymore (woowoo)

But I am sexually active, but I always wrap it up with no slips and he's kind enough to pull out.

(Sometimes I even check for holes just to be safe ;] )

Am I totally normal for being paranoid enough to take a pregnancy test(negative) because I'm technically 2 days late now? Anyone else stop having periods while on BC? How did it happen?
