Does progestogen-only / Mini pill cause lighter periods?

went on this pill due to high blood pressure, and the experience has been very well. my periods skip a month then return lighter. the first month my bleed was longer but lighter, ever since then it has been lighter. my period cramps have reduced massively. few headaches and light sensitivity but has not occurred in a while. acne has be a little bit worse and oily but clears up after a bit. overall has benefited me and libido increased surprisingly 😊

My periods were only irregular/spotting for the first 4ish months while my body was adjusting to the hormones, after that my periods became regular again and lighter than before too. I also believe this mini pill has not effected my mood, breasts or weight.

Loss of sex drive and mood swings were especially bad for the first 4 months or so. It since has gotten better, but I don't think it's back to normal. I have gained about 10-15 lbs since I've started the pill and I have also bled (more spotting than normal period flow) around 5 days during the second week of the pack and never (or so I recall) during the last four days of the pack. While I'm spotting I have pretty constant cramps, which I didn't have before.
