Birth control

This is my first time using the pill, when I started using it I was expecting my period in about a day but i had to start on that Sunday as instructed by my OBGYN (so the hormones stopped the period) , I’m starting my first sugar pill tonight, I was wondering how long after I take the sugar pill should I expect a period

I’ve also experienced some bloating around my lower abdomen pelvic area, it’s very little but it’s enough to where i notice it, is this unusual?

If it helps I’m using Junel FE
