Pregnancy after miscarriage? Or left over Hcg?

Alyssa

I posted in here 2 days ago explaining that I had a still birth at 22 weeks on March 1st. I am currently 21 days out and I am still getting positive pregnancy tests. The first pic is from 2 days ago and the bottom pic is from this morning. You guys think it’s still left over hormones? I got a positive opk on the 10th and we baby danced on the 11th... so I’m really wondering now. But it seems too soon. Ugh! Any insight ladies??
