Feeling sick baby not moving as much?

Bree • I`m 27 yrs old and have one son (8). I just had our second. Not sure if we're done or not.
I'm 36 Weeks. Yesterday I started feeling sick to my stomach. I took a "nap" to see if that would help. NOPE. I woke still feeling sick. She was moving a little bit after that. But come 9:30 when it was time to go to bed she didn't move and this morning she hasn't moved wich she usually does. My stomach feels tight. And I still feel sick. I'm getting worried.
