Keeping gender secret

My family keeps asking me in the group chat when will I find out the gender of my twins I told them I don’t want to find out in other words I do not plan to tell them the gender I actually want to move away to my bf house and just go m.i.a they’ll never travel that far to come see me and I’m fine with that i don’t want a gender reveal party or a baby shower I get that these twins are the first ever in my family but far as family goes I only have 3 immediate relatives & their kids I know I’m entitled to feel this way but a part of me feels I’m being extra i have a 10yr old so it’ll be almost like I’m starting over as a ftm because of the gap my brother has quite a few sons me and my sister also had boys first then she had a daughter my sister is already salty because their is a chance my babies could be girls and her daughter is disabled it’s just so much with my pregnancy thoughts and I’m high risk as well and i just want to scream
