Please help me... 😩

So.. I had a miscarriage on the 3rd of January, I was 18 weeks and had a d&e.; I bled on the 7th till the 15th. I then started taking tests and they became negative within a few days, I took and opk a few days later which was negative and then started doing them regularly and got a positive on the 21st, & 22nd, I’ve just taken a first response test which has got the faintest lines... would this be the old pregnancy or a new one? I’m really hoping it’s a new one and convinced it’s a new one since I was getting negatives on strips for a while before and during ovulation. But is it possible? Help please!
