You make an interesting comment that no one has commented on. What do you mean by “coming into the Church”? Were you not Catholic before that?
If you were not Catholic before that, then it would be incorrect to say that your marriage was invalid. If you were not Catholic, you were not required by the Church to follow the form of the Church. Your marriage would be valid, but not sacramental if it was, for example, before a Justice of the Peace.
If it was before a minister, then I would let someone with a stronger background than mine in Sacramental Theology answer whether or not the Church would consider it a sacramental marriage as of 8/30. Considering that the Church requires those married in other Christian Churches and subsequently divorced to go through an annulment proceeding before being married in the Catholic church subsequently, it may be considered not only valid but sacramental.
