Once TPR happens, how long does it take to adopt?

I think New York gives the bp 30 days to contest. I have a feeling the ** will contest. It will be interesting though,because she is pregnant and due in December. She may sign away her rights to try to keep that child, but I highly doubt it. She is a fighter. Don't know how much more of this I can take. I've just had about enough of this nonsense and just want peace and stability without worrying. Thank you for your replies!
