Am I having a miscarriage?!

Charlotte

I'm 4 weeks 6 days pregnant, I found out I was pregnant last week which is the photo on the right hand side, but yesterday I started bleeding it was only light but today it's more like a period a lot heavier and a lot darker, I took another test today (left hand side) and it seemed abit more faint than last week, someone help please! Am I still pregnant or? What could the bleeding be?
