Has anyone gotten pregnant soon after a D&C?

In March, i had a missed Miscarriage of my little girl. 3 days later, i had a D&C.

My HCG levels were followed all the way down with blood work.

I had one period on the strange side.

Two days ago, i got a glaring positive test. Immediate shock set in, as i wasn’t expecting it to happen so soon. I’m a little worried, and have been a mess all weekend.

Has this happened to anyone else and you had a normal, healthy pregnancy?

Picture of test attached.
