Calming Nerves

emja0214

I think I am beginning my 5th week tomorrow, I go to to the doctor for my first appointment on June 5th.  This is my first pregnancy and I am SO nervous.  I keep on over analyzing every little feeling.  I have been having cramping for a couple of weeks now, which I know can be normal.  Today it has changed to a dull pain/discomfort and pressure in the groin area.  Is this normal?  How do I calm my nerves so I can actually be enjoy this wonderful time?  June 5th cannot come soon enough!
