Cramps and spotting 5 weeks

Jan
Hi 
I'm just over 5 weeks and spotted light brown all last week. I thought it was the start of my period. 
I tested positive yesterday for the first time and was over the moon 
This morning I had more light brown spotting followed by a more wet reddy brown discharge in my pants with a tiny clot?
I'm worried that this isn't going to end well
Has anyone else had this?
