Assalamu Alaikkum wa rahmatullahi wa barkatuhu,
Sister, it is your preference. There is also a hadeeth which says you can say - “SubhanAllah walhamdulillaah, walaa ilaaha illal Allah, wallaahu Akbar” 25 times.
It was narrated from Ibn ‘Umar radi-Allah an’ that : A man saw in a dream that it was said to him: “What does your Prophet (salalahu alaihi salam) command you to do?” He said: “He commanded us to say Tasbih thirty-three times following the prayer, and to say the tahmid thirty-three times, and to say the takbir thirty-four times, and that makes one-hundred.” He said: Say the tasbih twenty-five times and say the tahmid twenty-five times and say the takbir twenty-five times and say the tahlil twenty-five times, and that will make one hundred.” The following morning he told the Prophet (salalahu alaihi salam) about that and the Messenger of Allah (salalahu alaihi salam) said: “Do what the Ansari said.” (Hasan) [Sunan An-Nasa’i in the book of forgetfulness of Prayer).
