Changes in Mini Pill behaviour?

My (M32) friend (F32) has recently changed to the Mini Pill, as far as I'm aware, it's the Pill with just progesterone in it.

She's been taking them for about 2 weeks now; to the women that changed from the one with all three chemicals to the Mini Pill, did you feel any different? Were your period cramps worse? Could you feel your emotions affecting you more? Did you start to notice when the periods where coming on?

TL;DR- friend started taking the Progesterone-Only Pill and I'm wanting to learn a little bit more about it
