Help please!?

So I had a miscarriage on 12/31/19 and on 1/31/2020 I took 2 pregnancy test and this was the result.

I will be exactly 4 weeks and a couple days from the miscarriage I had back in December and everything was back to normal except no AF, I even did a test about a week ago and it was completely negative so would this be a new pregnancy??? Extremely confused first time this happens to me
