Not felt the baby kick yet

I'm 21W1D, and I'm still waiting to feel the baby kick. My anatomy scan is after 2 weeks, and my anxiety is killing me. All I can think about is if my baby is fine. It's my first pregnancy, and my belly hasn't rounded up yet. That concerns me, too. One of my coworkers recently said that I don't look like I'm in my 5th month. We went for an ultrasound last week, and the baby was active. Is it okay for not feeling the baby kick by this time in the pregnancy and for the bump to not be rounded by now? 😒😒
