Sorry for such a long post but plz help and read whole thing before voting

I've been on the progesterone only pill for about 5 months and I went on it to try to shorten and lighten my period but although I don't get cramps as badly I wouldn't consider them being lighter and they are so much longer, I never have spotting it's always full periods and my cycles messed up so I want to know whether this is normal for the mini pill or should I go back to my doctor. Also I can only take the p.o.p due to migraines and severe nosebleeds for some reason it won't let me upload a photo but here's the data sorry it's so confusing...
