Do I bite the bullet and go to the Dr?

I have had a nasty cough since Thursday... I FINALLY got around to calling my OB yesterday and asking what OTC meds I could take...

They said plain robusstin was fine...

So I took that yesterday and today, but it seems to be breaking things up and making it worse... (which might be a good thing???)

Im totally avoiding going to the PCP- since I dont have all day to sit there, but I also dont want to allow this to turn into something worse if there is an infection...

Ergghhh.... "Tis the season"....right?
