I had really terrible bloating with Hana unfortunately. My periods were also irregular. Maybe would of been ok if I stayed on it longer than 2 months but found the bloating a bit too much for me.
I was apprehensive about taking a progesterone only pill as I have friends who didn't get on with it but I have been very pleasantly surprised. I'm on my 4th pack and have had 1 period in that time. The only notable side effect is vaginal dryness. I still get wet during foreplay/ sex but definitely not as much.
I had extremely painful periods to the point where I was missing work every month. After trying and failing to get help from my GP, I bought some Hana over the counter in an act of desperation. It's helped immensely with my pain (not gone away, but doesn't debilitate me anymore) and has had the unexpected side affect of making me calmer in general, presumably due to this pill balancing out my hormones. I don't get depressed or hysterical around my period anymore, and feel more in control of my emotions. Glad I tried it.
