Swearing on Quran

Salam . I am a married woman with 2 kids . I have been smoking ciggs for 6,7 years now . Ever since I moved to uk and especially after kids , I started smoking more . My husband caught me smoking a week back and forced me to hold the Quran and ans his questions . He asked when I started smoking , I answered that I started after my second child was born although in my mind I was thinking “restarted “ as I had quit during the years I was pregnant and didnot want him to know that I had been smoking for so long . I was scared he might take a big step . Although afterwards I held the Quran again and answered all his questions correctly stating it’s been more than 7 years . I am now very concerned as I think I might have swore falsely on Quran .
