38 weeks and vomiting

Samantha 🎀
I woke up last night gagging on vomit.  I ran to the bathroom and thank god made it to the toilet.  I threw up for a good 15 minutes but it was all just bile and no food.  Has this happened to any of you ladies?? Now I'm so sore and I feel like I pulled every muscle in my back and abdomen.  Could it be an early labor sign?
