Nerves Nerves Nerves

Hi Ladies, I'm 5w4d today.  I'm feel fine physically but mentally I'm scared sh**less.  I told my family on Sunday because we knew we couldn't hide it. This morning we had sex for the first time since we found out we are pregnant two weeks ago.  I was nervous about having sex because I miss carried in April just hours after having sex.  (Yes I am aware sex is completely safe during pregnancy but this mornings session still made me nervous).  I'm OCD about planning things and I'm a crazy list maker.  My first ultrasound isn't until July 13 and the wait is driving me nuts.  Ugh!  Am I nuts?  Is there anyone out there who understands this?
