Talking To doctor for first time

xoxo
Okay I don't wanna do anymore TTC things until I discuss with my doctor the fact that we're TTC and I wanna get tested for everything to make sure baby and mommy will be okay throughout entire pregnancy and beyond. This will be my first time seeing him (well since he delivered me) and Idk what to say cuz obviously he'll probably look at me and see his daughter who is the same age as me (20 about to be 21) and wonder why I'm TTC so young. My question is how do I talk to him about this? Really don't want him being judgemental or refusing to help or anything cuz ill feel all embarrassed I'm a shy person so like a turtle I will retreat (lol)
