Pregnant right after miscarriage

I had a miscarriage on November 3rd, and never got my period. I tested because when my toddler was breast feeding my nipples were really hurting. I had 2 before I got pregnant with him. I had tested a few times after this miscarriage to make sure the test went negative and they did. In shock honestly that it happened right after this one. So I’m hoping this a sticky baby and everything turns out good.
