Anyone else freak out at lack of symptoms in 2nd trimester?

My whole first trimester i was getting sick 2-5 times a day lost a lot of weight (32lbs) and was constantly miserable but whole time delighted at being miserable. Not I'm in the second trimester (15w2d). Let's just say I am constantly worrying something is wrong. I haven't felt baby move yet. I don't have a bump to speak of. Symptoms i do have are round ligament pain in my abdominal and back as well as heartburn, and dizziness. I have 5 wewks until my next ultrasound. Anyone else feel like they were going crazy with worrying and wondering?
