I had to walk to my prenatal appointment?

I'm pregnant and I had an appointment yesterday morning. Even though it's only 15 min away ( walking distance). My husband who has a car... when I asked him if he could drop me off... he got annoyed and said you need the exercise you should walk... I was extremely pissed. Do you think I'm over thinking things? I feel no support.
