Lost custody of children years ago...pregnant again

I hope to not receive a lot of cruel and mean comments here but nonetheless I'd like to reach out. I know there are millions of non custodial parents. How many their are that are impacted by not seeing their other kids whether full time or not at all is way to high. I would really appreciate it if I could connect with those mom's. I'm thrilled by my pregnancy I just miss my children I already had terribly. Again I hope to gain some support and kind words at least. Thank you
