In denial with these tests

I'm finding it hard to let myself get excited because I don't know what to think of it.

I've taken pregnancy tests within the last 3 days, different brands and they've come out positive. I had a miscarriage 6 weeks ago and haven't had a period since. A couple of days before I miscarried, I had negative pregnancy tests. since then I was taking pregnancy tests to make sure that they weren't coming out positive. Then when I took the ones Friday, Saturday and today they've all come out positive. My hcg levels were really low when I was pregnant before I miscarried so I wouldn't thing that it would be leftover hcg. The first 3 were taken first thing in the morning for the past few days. The test strips were taken this afternoon.
