Steroid shots and fetal movement decrease...?

Ra

I had a steroid shot test at 34 weeks for baby’s lungs, after the shot he was his usual very active self. Today after the second shot I have had very little movement. I drank orange juice and ice water and laid on my left side for 2 hrs. I was able to get 11 kicks (dr said to call if I had less then 10 kicks in 2 hrs.) but this is still a major decrease in activity. Had anyone noticed a decrease in fetal movement after steroid shots?
