18 and want to start ttc

so i just turned 18 and i want to start ttc, my whole life i have always known that i wanted nothing more than to be a mom and to have a baby, i live with my boyfriend in an apartment that we split rent on and we have a car and decent jobs , (he has two). i guess i’m just wondering like would my ob take me seriously? like when i telll them that i want to start ttc? i feel like everyone is going to be trying to stop me and talking me out of it but this is most definitely what i want and i’m stable so why not? i know very well what having a baby brings and requires , my mom had twins and she was always too drugged out to care for them so i always had to, and i’m not saying it’s the exact same because they weren’t my kids but i know how hard it can be x2. Has anyone had any experience with this? any young women ttc ? do y’all get treated any differently??
