How to break a BFP to a friend with fertility issues

No one knew me and my partner were trying for a baby not even any of my friends so this includes her.

I am waiting until after my scan to tell people I am pregnant but I'm wondering how I will tell her. I do not want to do the whole let her find out for herself sort of thing when my belly starts to show.. (she's also my neighbor) but I keep thinking of how it hurt when people told me they were expecting and I hadn't got my BFP. And I don't have any fertility issues, therefore I know it will hurt her and I don't know f she'll be able to hide any emotions if I tell her face to face.

Does anyone have an experience in this sort of thing? How did it go? What did you? 

Any help would be great, thank you.
