I'm 17 weeks pregnant and have noticed that I have a heavy feeling in my arm and leg. I do suffer from health anxiety and have done for years. I've been to the doctor numerous times about this and she has said she isn't concerned about it. Could it be pregnancy related? I don't get pins and needles but my leg and arm on my right side feel heavy and weak. The more I'm focusing on it the worse it is but I just wondered if anyone had felt the same.
