Hello, I think it's great that you're getting a lot of feedback but slightly unsettling as it's all very pro keeping the baby which is great if that's what you want but maybe doesn't help you explore all the options.
There are some great websites that have structured activities to help you to make a decision. One is from the royal women's hospital in victoria, australia. They ask a series of questions- about 20- about each option ie keeping, terminating and adoption. These questions really help you to think everything through.
Another great website is www.childrenbychoice.org.au. they have an information sheet which guides you in your decision.
I think both of these options will help to take you out of the frenzy of indecision and help you to clarify what you really want.
and for what it's worth, I think it is important to listen to your husband's needs and wants too. One of the counsellors I spoke to said it was essential to consider the impact on everyone in the family. My husband is a great guy but he also doesn't want another child and I understand how he feels.
I really do think a counsellor could help- even if it's only online.
Best of luck.
PS I got some stats about how women feel if they terminate- from longitudinal studies which are scientifically backed up- and the prognosis wasn't that bleak. The women who really suffered afterwards were those who felt coerced into the decision and those who had some mental health issues beforehand.
