Missed Prayers and Fast due to not knowing about rules

As-salaam 'Alaykum. I got my period in almost two years ago in 2019. I was 11 when I got my period. I thought that praying and fasting were based on age. This year was the first year I fasted for all of Ramadan and have been praying consistently. I was not aware that once a girl sees her period that fasting and praying become mandatory. Do I have to make up the prayer and fasts that I missed even though I was didn't know I was supposed to?
