Anyone get pregnant right after a birth and was it successful?

Sh

I just had a baby 4.5 months ago and I am already pregnant. I am 4+4 (approximate), I haven't been officially dated yet. Has anyone gotten pregnant right away after a birth and was your pregnancy successful? Or did it end in miscarriage? I am nervous I will miscarry again. But from what everyone says, you are really fertile after pregnancy. But does it usually mean your body is ready to take on another pregnancy or is it harder to carry to term bc you just had a baby? Ugh. Any advice is welcome or your own experiences with this. Thanks y'all!! 💙💗💙💗
