5 weeks pregnant and fell

Help! About 4 hours ago, I was getting out of bed and slipped. I went straight down on my bum and my knees were bent. My back slid down the bed. I’m not exactly sure how hard I hit the floor, I don’t think very hard because I’m not in much pain. But I completely freaked out thinking I hurt the baby. I’m not really have any cramping that I haven’t been having, and I’ve not noticed any bleeding. Am I in the clear? I’m freaking out and of course it’s weekend I can’t call my ob.
