I can't log into my instagram!?

[G A B B Y]

First I thought it was my internet.
But well...4G and full bars.
I went on the internet on my samsung galaxy S3 instead of my app...but it worked fine.
But of course I can't do the same stuff.
I have 4 accounts..
I can't log into any of them.
How could anyone spam them all?!
Urgh this is fustrating,
What am I doing wrong.
I'm 13, and i don't do anything bad on IG. Help e.e
