there is to much missing info in OP to answer, and since every situation is different, can’t answer with authority about an individual situation here. the priest should interview you, in fact should have already done so, and that is where you lay out all the facts about your marriage, your baptismal status, previous marriages, and so forth so he can give you a solid answer. The general rule is that marriages between non-Catholics who are otherwise free to marry are considered valid, and if both are baptized, are also considered sacramental. If non-baptized persons who are validly married receive baptism, their marriage becomes sacramental as well, with no other action needed.
complications arise when there are previous marriages, when one party was baptized Catholic, for example, so unless the priest has all the relevant info, hard to do in a casual conversation, you can’t get an answer that applies to you.
oh, and welcome home to you and your family.
