expecting AF Thursday #sheisntwelcome

Adriana • Married almost 2 years....TTC baby #1
This is my first time posting.....
My husband and I have been TTC for 7 months and several times we thought we were close to getting our BFP 
In the last week I have been so tired, hungry, go to the bathroom more often, having some back and abdominal pain, and Sunday I developed a new symptom I've never had....when I am still my insides seem to be shaking (like when you drink too much caffeine) 
I googled and it said it could be from anxiety, I haven't had this problem in the past....a friend of mine told me that she had this symptom in the beginning of all three of her pregnancies
I took a test this morning but it was negative.....
Has anyone else had this symptom?? 
**thought I would give an update even though no one has commented......AF didn't show up today
