I’m pregnant after my bestfriend’s miscarrige!

My friends and I are all in our mid 20’s. Out of our group nobody has a baby. Last year my bestfriend, who is also my cousin, had 2 miscarriages. She was distraught and has been trying to get pregnant since with no luck. I just found out that I am pregnant and I have not been trying. I would have liked to wait, but my child is a blessing. She will be so hurt and I don’t want to be the source of her pain. But I also need the support of my friends. I can’t tell none of them because I don’t want her to find out through somebody else. How am I going to tell her the news? Should I give her the honor of being my child’s godmother?
