Any of these symptoms mean anything?? Slept maybe 3 hours last night. Woke up with right shoulder pain although I slept on my left side. I haven’t been able to lie down comfortably on either side or sitting up since i woke up around 730am. Braxton hicks pretty frequent. And I’m really nauseous. Haven’t had any nausea this last trimester. I have eaten and drank water and still no relief. Any suggestions?? Is labor coming?
