Surprise I'm Pregnant...I think.

So I went to the OBGYN last week for a regular visit and they did a routine pregnancy test.  It came out positive!  Hello surprised - very pleasantly surprised actually! 

We weren't sure how far along I was b/c I have PCOS and don't ovulate like normal so we couldn't go off my last period.  This week I did an ultrasound which determined I'm 5.5 weeks pregnant but the ultrasound only showed a sac - no yolk.  The doctor said it's still early so it's normal not to see much and everything is probably fine but there is a 30% chance that a baby doesn't form.  He said I should come back in two weeks for another ultrasound.  How am I going to wait two weeks.  Gosh I'm nervous.  Has anyone experienced this?
