Scam email link to legitimate site

I received a invoice from my Internet provider. I use the link in the invoice to sign into my provider. As soon as I saw the amount I realized that the invoice that I had received was a scam. My question is the link in the scam email went to my real provider I signed in and it was my account. I have since changed the password on the account. Is there anything else that I should do. I was using an iPad at the time.
