Freaking out! Please help me!

Claire • 16 wks baby!!!
I fell on Wednesday, and I had just started to be able to feel the baby kick pretty strongly and consistently. The workmans comp dr said I am fine, and I feel fine, especially since I continued to be able to feel the baby kick on Thursday Friday and Saturday... But yesterday and this morning I have felt nothing, and it's scaring the heck outta me. Am I freaking out for nothing??
