In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
Circumcision is not a condition for nikah. Your nikah was valid and no act of zina was committed. Your relationship with your wife in an uncircumcised condition is halal.
Circumcision is a noble act and a Sunnah of the prophets Alaihis Salam. As an adult you may still be circumcised.
And Allah Ta’āla Knows Best
