Anyone Else?

Jessica • Married 5.7.16 --- Finishing my last year at OU and working as a freelance photographer.
So a few months ago my period just decided to stop. 
I am not pregnant. (Took a blood test and all.)
The doc said this is just something that happens to people sometimes due to the hormones in the pills. 
I've been on the pills for 3 years. This week marks another month of no period (yet). 
Has this happened to anyone else? Did it ever start back up?
I'm not complaining, necessarily, just curious. :)
