How cushioned is baby....

I feel like I’ve continued to work hard and do things some pregnant woman wouldn’t do at times. Example how much I have lifted/carried at work. I know they say your body will tell you if it hurts and that whatever your body is used to doing should be fine to continue. Also as well has how hard I have pressed down on my belly to feel my baby. I feel as though he is very safe and cushioned in there but now I’m starting to feel bad all the stress and tension I may have caused him😔
