Nervous wreck!

Iv wanted this so bad now that I've got my BFP I'm so anxious its awful! I'm constantly worrying and freaking out. Another thing adding to my nervousness is the fact that I don't have many sumptoms. I suffered a loss in the beginning of June, I'm so very stressed, I really don't know how to make it go away, this ill feeling in the pit of my stomach all the time. I make myself 5weeks and 1 day today due 14th April 2016 God willing. Anyone else feeling anxious and what do you do to make this feeling go away? 😔
