For the record here is where I found it:

Perhaps I did misunderstand?
The EWTN expert gives his opinion, one he readily admits that Rome would not adjudicate the same way.
He is overstating the situation, really didn’t do a good job of distinguishing what exactly renders a marriage invalid via canon 1101.2 which is MORE than simply using contraception. Use of contraception
could be evidence of such intent, particularly if one spouse asks for non contracepted sex and the other refuses, contraception is used permanently or one or both are sterilized prior to marriage or even in marriage, conception results in an abortion, or other such evidence of a
permanent intention against children.
It is a
specific act of the will prior to the marriage, either one spouse or unilaterally, that the couple (or the one spouse) does not want or intend children to be part of the marriage, period. It’s called Partial Simulation Against the Good of Children. If one spouse hid that from the other, then you possibly have other grounds related to conditional consent, fraud, etc.
The bottom line is, just because you used contraception as a Protestant it does NOT mean you have an invalid marriage.
Did you and your husband have a permanent intention against children at the time you exchanged vows and does that carry to the present day without a change in the will?
If the answer is no, put this out of your mind, don’t let random things you read here or anywhere else trouble you so. If you have a sensitive conscience, get under the care of a priest or spiritual director.
