Would my period stop if I got pregnant??

If I was to get pregnant while taking the pill, would my periods still stop? 
I know that when you get your period on the pill it isn't a real period. So I am unsure if it would stop or not. 
If I continued to take the pill (not knowing I'm pregnant) would I get a period each month due to my pill causing the bleed on placebo pills?? 
Iv taken a couple of tests just incase and they were negative. I still got my period the next month as well.
