Faint line at 8 weeks and 2 days

Vicky
Hi ladies, 
I'm currently 8weeks and i'v got cheap internet test. 
I tested this morning as last month I suffered a chemical and just really scared it's going to happen again. 
But it came up really faint! 
I still feel sick my boobs have stopped hurting and i'v had no bleeding or cramping, so I'm really confused 
What do u ladies think, should I be worried?
