Nothing wrong with that. Most girls aren't regular in their cycles for a year or so... don't wig, you are fine. But if you are really concerned, you can go to a doctor and they can put you on medication to regulate your cycle.
i got my period when i was 10 years old and it was regular from the very start
The medication to regulate is birth control pills; they prescribed them to my friend at 13 for just that and they gave her chest pains after a couple days so she had to stop taking them. Dr. said young girls can have small blood vessels and the pill wasn't a good option in her case but she became regular within that yr anyway.
Yes, that's normal. My period is still irregular, and I've have it since I was 14. Just carry some supplies and quarters with you, just in case.
