Is it normal for your period to be irregular for 4 years? If not, is it something to be concerned about?

This is getting ridiculous! I haven't had it for 4 months now and the last time I had it it was for 2 days. Then before that it took 2 months, and its just entirely out of whack!

I get it being irregular for the first few months after first getting it, heck even a year, but its been 4 yearrssss. How do I fix it?

I've lost too much clothing cause of being caught by surprise!!!
