When should I call?

I had bloodwork done for cholestasis yesterday morning and a steroid shot. I received my second steroid shot this morning.

Baby was active as usual last night around 9-10. I barely slept last night thanks to insomnia and there was a sharp decrease in fetal movement. On the drive to get the shot and back, usually baby boy goes nuts. Nothing. I chugged 2 and a half cups of OJ when I got home and have been laying down in his favorite position for half an hour now and there’s movements, but nothing like usual.

I’d say his activity and movement is down 75%. When it comes to how often, how strong, and usually how wild and all over the place he is? I’m concerned. Should I give him more time to perk up before calling my OB? Another half an hour? Call now? Is it the shots?
