My understanding is that the "period" you get with hormonal contraception is not actually a period. It's breakthrough bleeding- irregular sloughing of the endometrial lining- unconnected with the normal hormonal fluctuations on the menstrual cycle. The key word here being "irregular"- which would account for the "on and off" bleeding and the fact that you saw bleeding just 2 weeks after the first time.
In short, no, this is not your period's new normal because this wsn't your period, and it's probably ot something to be worried about because this sort of bleeding is a common side-effect of hormonal contraception.
