I missed 4 days of my birthcontrol pill?

It's middle-of-the-road. Same thing happen to me. I was regular though most of high-ranking school but have severe cramps. It wasn't until my senior year through my freshman year of college that I was very irregular and would sometimes run two months without have my period. I finally go to a doctor and she prescribed birth control pills. It really helped to regulate my period but didn't help beside the cramps too much. Now I'm on a generic brand of sesonale so I only seize my period every three months. It's great! So I would have a word to a doctor about starting a birth control pill or dawdle and see if it regulates on its own.
