am i a mess?

so i'm 16, not sexually active, on my 3rd month of low dosage birth control pills, and im on it for period cramps bc mine were horrific. i have never missed a day of taking my pills but i don't take it at the exact same time? i have an alarm set for 9:30 am but i usually end up taking it anywhere from 10-2 (on a bad day). my period was VERY regular before i got on the pill, but now it's different? and also i heard from a friend on it for the same reason that it gets worse before it gets better, but i occasionally get cramps that only last a minute or 2 but they are the worst pain i have ever experienced in my life. also i don't get my period on the week of placebo pills (my period is 9 days long but it has always been). is this bc i don't take it at the exact same time, should i wait it out, or should i ask my doctor to up my dosage? lol thanks if you read all this
