Scared.

Ok,so I'm at work today and I can't seem to shake the feeling of worrying about loosing my baby... I'm 6 weeks tomorrow,I've had the occasional cramping,hardly anything to worry about! No bleeding,nothing like that! I just can't shake it! I've tested a few times now and everything is coming back positive! I don't have the Drs for another 3 weeks,I don't want to miss a single thing go wrong.
