The pain is definitely normal. I was scared at first but it stopped after a few days. And I also did not start to really feel my baby move until a week ago and I'm 20 weeks. Everyone's pregnancy is different so as long as the doctor says you and baby are healthy then no worries :)
Well I work all the time and I'm always on my feet. I just been pariod where I can't check on it all the time...
The pain is probably just ligament pains and stretching pains. I didnt feel much movement until around 23 weeks. And i didnt start to really show until like 25 weeks or so.
