Knowing him from the palm of your hands

So I have this appointment with my high risk doctor and my boyfriend wants to go but I know what my dad going to say, like last time he told him he wanted to go and he said no for him going to the ob doctor and I told him he got right to go and he got really mad at me and that really stresses me out and I know he isn't going to understand cause he loves stressing me out. Last time he told me he does have rights just cause he just only my boyfriend and not my husband 😔. I don't know what to do. I shouldn't be stress but I am. I know I'm old enough but I can't if I don't have a job, my boyfriend lost his, he lives with his parents and I just want to leave. Just me thinking it just stresses me out. If I tell my boyfriend he'll get mad as well and I know he got right go see his baby and join me for the appointment. 😔
