I had sex before marriage and got pregnant.

So I got pregnant before getting married. Clearly a sin. My husband's uncle is a Sunday school teacher and took it upon himself to talk about me saying how I pretended to be something I was not in front of the whole church. My baby is now about to be 9 months and I just found out because my mom finally told me. She also said how plenty of people from church were talking bad about me specifically versus my husband. Honestly this bothered me so much and I just want to confront them. Because to my face they tell me how cute my baby is. Any advice on how I should react to this
