Is My 2-hour Daily Sun Exposure During Early Pregnancy A Risk For Birth Defects Or Miscarriage?

Hello, I’m currently 6 weeks pregnant and am concerned as I have recently learned that extended sun exposure could lead to neural tube defects and broth defects to my fetus. It could also lead to miscarriages which I have had 2 already. I have been exposed to direct sunlight for 2 hours roughly a day since I conceived. Is my baby at risk for birth defects? Should I be concerned my exposure could lead to another miscarriage?
