Am I overthinking it?

Hello, I'm a 28 year old female who is very independent and career oriented. My husband and I have been together since high school and married five years. I really love him, but he's always wanted kids and I've wanted to wait. I have finally started to feel that I am ready, but when it comes to actually having sex, I can't help but question my choice. I find myself going back and forth on whether now is the right time. And frankly, it's just been a bit awkward to have sex. it's hard for me to be in the moment when I have some much running through my mind. any advice on how to have sex for conception?
