Is this common?

How normal is it to lose symptoms? 
My breasts have been very tender for over a week, and today they're not. I'm 5 weeks and 2 days along... 
Very nervous and worried because my last pregnancy this happened and I ended up miscarrying. 
I know I shouldn't worry, and that God is still in control. 
I still have an increased appetite and haven't had any bleeding yet. But I'm still scared. 
I need some reassurance. Has this happened to you before? Did you end up going all the way and having a healthy pregnancy and baby?
