How to break a santeria curse???

Let me start by saying I don't believe in santeria (and I'm not knocking anyone who does). My husband's ex wife hates me, she is still in love with my husband. They were divorced 5 years before we even met, I didn't take her man. She practices santeria and told him a few days ago that she was "doing her part to make sure we don't have a child" and laughed about her comment. I think maybe she did santeria on me!! We've been ttc for a year and had a miscarriage at 10 weeks... does anyone know about how to break a hex, is this an evil eye thing? Idk, but I think I should do something just in case!!
