Is it appropriate to call my Mother in law mi “Suegra?”

Estoy practicando mi Español. Mi “Suegra” es de Puerto Rico. Ella habla ingles… pero quiero hablar y aprender mas. Ella es la mejor, Me encanta! Mucho!

I think “Mother in law “ can sound a little distant in English. I call her Mami. As she has been my mother figure since my Mom died. I do love her with all my heart. I know Suegra is the translated term for “Mother in law.” I want to know if that’s a “warm/loving” term en Español? (Puerto Rican) Or is there a better way to refer to my “Mother in law?”

Por favor, Yo quiero respuestas genuinas! La quiero mucho!
