Salam kerrigwen,
How do you mean she is unsure? Like whether to keep it or not? I know this is not entirely answering yor question, but it is very important that she know that abortion is not allowed unless there are exceptional circumstances, and "too soon" is not one of them.
Really, I think it's best to talk to her about Allah's qadr and acceptance of it. Like you rightly said, babies are a blessing. They are a joy, an opportunity for women to take part in Allah's creation of life process. Also, we think we can plan for major things in life like babies, but really we can't. Take the example of a couple who try and try to get pregnant, but no matter what they try, it wasn't in their kismet for a baby to happen. Likewise, a couple where the women takes the Pill, and the man uses contraception also, and still the woman falls pregnant. Plans are not foolproof, they are not certain. Yes, we have to work and plan to the best of our abilities, but sometimes things happen despite our best laid plans. When that happens we have to accept whatever happens, good or bad, and say alhamdulillah and count our blessings.
Also, it may be worth talking to her about exactly what is worrying her. Is she worried about the financial implications, about the relationship between her and her husband, etc? It may be helpful for her to talk these things through with a friend, like yourself, and maybe once the things she's worried about resolve, she will be able to see this pregnancy in a different light.
Anyway, all the best, inshallah.
