From when I was muslim?

Assalamuâlaikum, Before I reverted, I studied about Islam,was eating Halal food and occasionaly read Kalimah from kittab verbally and later asked my friends about right pronunciation. I used to listen Qur'an daily and used to think that "if I become a muslim, I'll pray 5 times, I will use this name and so on." However, I was not thinking that I was already muslim or not. As for my former religion(christian), to convert they need some special ceremony. I was thinking Islam may need as well. I would be muslim if Allah wills at any time. So I was waiting for a chance to be a muslim. I sometimes asked muslim friend to make duâ for me when he prays. Alĥamdulillah, he learned from scholar how to be muslim for me. SIMPLE step. Since, I try my best to practice upon Sunnah and started tabligh jamaah as I found it is the easiest way to practice Deen. Recently I found that I need Qada because I learned how to pray a week later after I read Shahadah officialy because I didn't have any Mahram nor lady muslim frineds to teach me. Those 1 week I was sitting down on the musallah at prayer time. My question is, from when was I a muslim? Not sure from when I started believing that Islam is the true religion. It may includes half of the Ramadaan period as well. Probably, I remember, when I used to join Iftari (without fasting) 2 years ago, I believed that Islam is the correct way of life, code of life from Allah. How many Qada do I need to do for Salaah and Saum?
