shoveling while your pregnant

Casey • Mommy to my adorable son Cayden Wayne
Hey Mommas! 
I have a question, I live in upstate NY & we just got pounded with 24" of snow these last two days & I just shoveled my car out. I'm 7 weeks & 5 days. Was that okay to do? My fiancé wasn't home & I was just trying get it done so I wouldn't have to do it in the morning. Should I have not done that? I'm nervous that I over exerted myself since I'm still early in pregnancy.
