Does progestogen-only / Mini pill cause headaches?

Generally a good pill but I am bleeding every week on it which is it’s main downside for me

I used Cerazette for 15 years and didn't really think about it, which is a testament to how few notable side effects I had. Worked effectively, and didn't hugely affect my appearance (skin or weight) which was very important to me when I began taking it at 21. However, I suffered from headaches / migraines almost weekly which I never connected to Cerazette until I stopped taking it, and since then they've gone completely (it's now been almost a year since I last took a pill). I've also got so much more energy, and my libido came back as soon as I got my periods back. Overall, if you can't take the combined pill and want a hormonal option, I really would recommend it, but be mindful that some side effects might come on slowly over years.

First few weeks were lovely, no noticeable side effects. Then came the breakthrough bleeding which didn't stop for months on end and still continues to this day at a minimal level. Couldn't fault this pill otherwise but the breakthrough bleeding is a major inconvenience and almost defeats the point of being on a form of BC. Breasts became slightly more enlarged and occasional lower back pains. I just wasn't one of the lucky ones for which bleeding stops completely. Periods are much lighter though but more drawn out. My usual 4-5 days are now 7-9 and that's not counting the daily spotting. It's been good as a temporary measure but I'll be glad to be off Lovima when the time is right because predictable periods >>> unpredictable spotting.
