I am with a child-free attitude for many years and I want (and I was) being frank: well, if you love each other, it's nothing. (I mean it's not a reason to poison your relationship with depression or to divorce and so on -- some couples react to the miscarriages very bad and they make the things worse). There are also others who don't mind it so much and even there are people who do abortions and they're pro-choice (advocating legalized abortion).
In this situation, all I wish to people like this couple is firstly to try to keep their love and then, later, best wishes and good luck with having a baby, if they really want it.
