Good progression?

I got my faint positive yesterday at 3 am. Then took a digital and got a positive yesterday around 8 am. Now took another First response around 30 hours later. I had a miscarriage last month with no cycle in between so I’m not exactly sure when my period would be due. So I’m concerned about a chemical. Would I like progress like this or be this dark if it were a chemical? Also, if any of you guys have had a miscarriage then went on the have a perfectly healthy pregnancy can I hear your rainbow stories? I’m SO extremely happy about this new pregnancy, yet so nervous. I was almost 9 weeks last time so it feels like a lifetime away to get past that point in this one.

First test taken at 3am Saturday

Digital taken around 8am Saturday

First test yesterday , second test taken right now. (30 hours apart)
