First time pregnant and I have a question!

Maryann
We are still super early and I am so nervous- just praying my baby stays healthy and happy inside me for these next 9 months.
My question Is do you think my "symptoms" are in my head?? I'm so early!! Only 3weeks 5days- haven't even missed my period yet but I have been starving all day which is not like me.  Other than cramps that's all I've noticed- is it all in my head?? It's not like the baby's needing food right now!
