Braxton Hicks scaring me to death!

I've been having Braxton-Hicks due to a yeast infection. Yesterday they were much worse than today but I'm on bed rest until they ease up since I'm only 21 weeks and also having back pain with them. However they are stressing me out SO bad, I've barely had any today but I feel like my body is turning on my baby. I don't even want to eat. I'm feeling some reduced movement too although I'm sure that's because of my change in activity levels. I'm so scared.
