My mom is mad at me cause I got mad at her

My mom is bothered with me because I told my family I’m pregnant before mentioning that I’m going to be getting married. I’m engaged, but she wants me to start telling people about the wedding before the baby shower. Just so that it looks better. When she herself is telling her friends I’m pregnant. She told me it looks weird that I’m telling people about my baby shower and not inviting them to my wedding. When I JUST got engaged and don’t even have a wedding date yet! She’s also very adamant that I get married even just by the courts for the “sake of the baby”. So if that’s the case why is she telling me I need to invite my family to a court wedding? I’m not even thinking that far ahead cause I’m pregnant with a bump! I told her I want to get married once my bump is gone and she told me to just get married by the courts and in the future have a big wedding. She’s now ignoring me because I told her to stop this nonsense when i don’t even have a wedding date and JUST got engaged. She is somewhat religious but I know it’s mostly so my family won’t think badly of me having a baby out of wedlock
