Pregnant or lost baby?

I’m literally sat here crying right now. I took my first test on Friday which came back with a faint positive. I then got my period just after that positive and then took these 3 tests (dates shown on picture) and still positive. First was taken with evening urine, second with morning and last was taken just now. I’m worried that I’ve had a chemical pregnancy (I had a miscarriage back in June) I don’t know what to think. My period came when it was suppose to be due but getting these positives is just throwing me off. They aren’t getting any darker either! Tonight’s is thicker than the other two but so I don’t know. Please help me.
