Really shaky!

Ka

Has anyone else experienced shakiness? I was just sitting at work and out of nowhere my hands started shaking really bad. I couldnt even hold anything. I ate a granola bar and pistachios and feel better but it seriously freaked me out! My blood sugar must have dropped. I ate a bunch for lunch so Im not sure why it happened so fast. Thank God I had snacks at my desk! Has anyone else experienced this? I am 11w6d.
