Help! Please!

So I took a normal test and the line came up faintly for positive, well I also took a test that said pregnant or not pregnant and it came back PREGNANT

so about a week later (today) I tested again just to see if mine got darker and it’s still faint but a little darker and i took another pregnant or not pregnant one and it still said pregnant.. I just also had a miscarriage in January so trying to stay positive! I go in for blood work on Wednesday!
