Sheila • 🌈👨‍👩‍👧
Are these the first signs of labor???
-Went from wanting to eat and eat and eat to now nauseous and barley want to eat 
-have all a sudden become super emotional 
-was up all night with terrible back pain and cramps and spent a good portion pooping 
-pretty constant back pain 
-overall just feel terrible.  Achy, exhausted, nauseous 
Thoughts?
