Instagram password reset email not sending? Please help!?

[Haven]

I forgot the password to my instagram account, so I went to reset password and typed in my account name. It said that an email had been sent, but it's been a day and I still haven't received an email! I've tried several times and each time it says it sent, there's no message. I've checked the spam folder, and I don't think instagram is blocked. I also tried entering my email address instead of my account name, and it said it sent, but no matter what I do I can't figure out what's wrong. I know I registered with the right email, because it says the email sent when I typed my email address in. Is this a problem with Instagram? Or my email?
