I haven't Been able to sleep for the last two hours. my dog keeps freaking out scared and running to me. which never happens. he won't leave my side. and now all of a sudden for the past 30 min I have been sweating so bad. I'm pretty sure it's probably 65 degrees in my house. I never have had night sweats or hot flashes. I am literally like soaked. is this a sign of labor or a new pregnancy symptom??
