Since you consented to this marriage, it is considered valid. There is no need to redo the nikah. Let me list below the essential requirements of a valid marriage in Islam:
The minimum conditions for the validity of nikah are the following:
1- The consent of the guardian of the woman
2- Presence of witnesses
3- Offer and acceptance
4- And finally mahr (dower).
Once the above conditions have been met the marriage will be deemed as valid; but if they are not, then the marriage is considered as being null and void.
Since your marriage fulfills the above conditions, there is no need for you to worry about its validity.
Almighty Allah knows best.
