Mini pill?!?! Help! !!

So I started taking the "mini pill" today (norethindrone .35 mg) and I'm wondering what people's experience is with it. Good bad and ugly. I am 33 and chose this pill because I feel my age and weight put me at an increased risk of blood clots so I didn't want to take combined but I'm just curious what I'm getting into. Some questions:

1. Side effects. How did you feel and what did you notice as far as side effects

2. Periods. My doctor told me my period may stop all together and be irregular. Did yours stop or change in any way ?

3. Mood swings ?

4. Nausea?

thanks in advance!!
