Disappearance of symptoms & worried :/

Melissa
Hi All, i'm currently 5wks & 3 days. It's my first pregnancy & today i've woken up with a distinct lack of symptoms! :/ I had slightly heavier cramping yesterday, which was a worry in itself. This morning my usually sore & heavy breasts feel normal again. I'm worried this means the pregnancy is not continuing.. Anyone else had loss of symptoms early on?
