I was on this mini pill for just over a year after switching from the combined pill. It slowly affected my mood to the point where my mood was constantly flat and I didn’t feel excited about anything. My libido was also very low. I felt a massive difference after stopping. Positives were I didn’t have periods often (every 6-8 weeks) and not much period pain. The 12 hour window to take the pill was also helpful when I sometimes forgot, as some other mini pills have shorter windows.

went on cerazette after trying out microgynon30ED and noriday (which both caused frequent irregular bleeding). My GP told me cerazette was fantastic for people who experience frequent bleeding on other mini-pills and often their periods stop. i started it back in late september 2025, and experienced bleeding every second week. fine, i thought, it’s just my body getting used to it! by november i was having just one period a month again! yay!! this was short lived however, as by december i was back to having it every 2nd week. in january i bled for 25 days straight. i was told that the first 3-5 months are expected to see changes in bleeding, so i stuck it out a bit longer. unfortunately the bleeding never stopped, and i continued to get my period now every week and a half, or sometimes even more frequently with only 3 days break in between cycles. :( it’s end of may now and have been on cerazette for 9 months. i am still bleeding every week and a half and honestly im sick of it. i have stopped taking cerazette now. hopefully there’s another one out there for me :(

I was a bit more emotional my first 1-2 months on it but then I was fine. Completely took away my debilitating period pains, I get one very mild cramp about once a month and that's it. No side effects except for some constant spotting. I Googled it and started taking 2 pills instead of 1 and the spotting has since stopped. My weight, sex drive, skin, and mood are unaffected as of now (8 months of taking it daily)
