Babies movements

Melissa • Mummy to two coming 3 (due August) beautiful children.
37 weeks, baby is still active enough and I still feel her movements but they deff haven't been as much or as frequent at all, normal at this point???? I'm starting to panic a tad. I have been feeling very tired, nauseous, stressed, and have serious heartburn. How do I get her to move so I know she's ok
