Swearing god

Back when I didn't know much about Islam, I used to occasionally say swear words like 'oh my ******* God'. I, by no means intended to insult Allah, and was mostly unaware of what I was saying, it would just come out of my mouth automatically. Did this take me out of the fold of Islam? If so, do my prayers between then and me coming back to Islam not count. I am very regretful for every saying it and would never repeat such stuff intentionally now.
