Chronic stress for entire pregnancy

I have been experiencing a moderate level of stress for my entire pregnancy. My job is quite high pressure and stressful, and I pretty much run on a baseline of being stressed. Has anyone else experienced this, and has it impacted your baby at all? My pregnancy has been fine so far and I'm nearly 30 weeks. I do worry if it will impact my baby's temperament and development in the long term though. Can anyone share their experiences with this?
