Does progestogen-only / Mini pill cause headaches?

After being off this pill for 6 months I have seen an enormous improvement in my mood, weight and overall well-being. I gained 9kg on this pill! I’ve been the same weight for a very long time, so to gain 9kg in a few months seemed odd but it was shrugged off as an ‘age thing’ as I’m approaching 30. Yet as soon as I came off this pill I lost the weight. I in part put this down to the extreme bloating I experienced on this pill. Insane levels of water retention stopped me from being able to wear any of my clothes. Not to mention the constipation! This had a serious impact on my well-being, self image and consequently my sex drive. Retrospect is a wonderful thing. Just wish I’d tried coming off it sooner!

Was always on my period when taking this pill, bled non stop for 3 months. Was horrible and gave mood swings. Stopped taking in the end as could barely have sex as constant bleeding, so wasn't even worth it.

It took me a while to realise that how I felt and what I was experiencing was due to the pill. I had been on the combined pill since the age of 15, but was moved to cerazette to see if it would help my migraines - it didn’t but I continued taking it anyway. I knew my constant moodiness and lack of libido wasn’t normal but I was too ashamed to speak to my GP because of bad experiences before. In hindsight, I wish I had because I feel my low mood really held me back.
