Some verbs change a bit more after ter, so you need more than just using a ‑do ending. For example, vir gets an extra n and becomes vindo.
Eles têm vindo aqui frequentemente.
They have been coming here often.
Here are two other verbs that change a lot: dizer becomes dito, and abrir becomes aberto.
Eu tenho dito isso aos meus alunos.
I have been saying that to my students.
Eu tenho aberto a porta todas as manhãs.
I have been opening the door every morning.
