Am I wrong? "Welcome to the world" Party VS. Baby Shower

Uni B. • 💋 Mommy to a Princess 👑💛
So I'm 17, currently 22 weeks pregnant and now struggling with some things. My mom had her first child at 15 and feels I'm "glamorizing" pregnancy. She says this because I wish to take maternity pictures and have a baby shower. She states that back in her days she and her parents were too shamed and that I should be ashamed and that I don't deserve to have a shower. She claims she's spoken with older mothers who've expressed they wouldn't come to my shower because I'm a teen parent. And that they basically don't like me so they wouldn't get me anything for the baby. So she insists on having a "Welcome to the world" party (after she's born) for just my baby.. but I don't want to. I feel it's disrespectful and rude to me as the mother. Am I wrong for feeling this way? I'm 17 and will be 17 in June when the baby is born. I'm turning 18 in August.. any advice? I feel so stuck and upset! I have 2 jobs and am honestly working my ass off for nothing.. I jus want to cry at this point.
