Irregular periods and other problems

My periods are irregular and my breasts hurt does this mean something? They're irregular because I'm on it now and I didn't end the last one long enough ago. Is something wrong with me?

Irregular periods are common, if you want to change that then I suggest you getting put on birth control because it really helps. As for your breasts hurting - don't worry, that will happen now and then. Almost every girl experiences aching breasts sometimes. Your body isn't done developing yet so you'll get odd feelings sometimes. If things start getting really weird though you could go see a doctor, if your worried. Periods can be weird sometimes; especially if your stressed or your body is going through changes.

My periods are irregular, and I googled it, and read about Polycystic Ovarian Syndrome, so then one time I was on my period for over a month, so I went to the GYN, and found out I do have PCOS.. so maybe go get tested for that?
or it could be nothing..
