Imagination or Symptoms?

I can never tell if I am having real symptoms or just convincing myself I have symptoms after reading what symptoms I "should have". Case in point, when I read side effects for medicines I'm taking, I start to have those symptoms. Really? Or am I just imagining them? The same thing is happening now with pregnancy symptoms. Not that I am not having those symptoms, but some of them can mean that my period is coming as well. Oh well, I will just keep waiting and taking a hpt every couple of days (still negative as of Monday). I really want to save up some money and go to a Reproductive Endocrinologist (my insurance doesn't cover it) because I feel I will get better care there. My regular OB/GYN is just not cutting it. Anyone want to give me the name of their awesome Phoenix based OB/GYN with me?
