Weird question but the past 2 days I haven't been feeling the greatest startded loosing my mucus plug, diarrhea tmi sorry, Braxton hicks, back pain, nausea..  I'm 38 weeks tomorrow. But my dog has been acting really strange today.. So I was wondering if dogs can sense labour is coming? My dog acted super weird like this before I even knew I was pregnant also
