Family

Hi, I am currently 9 weeks pregnant. Discovered I was pregnant at 2 weeks, pretty early. First response, shocked, tears, scared. As you can imagine, it was really unexpected. On to the family part. I have only told my mom. I have 2 older brothers and other relatives. I'm no longer close with them because ever since my father passed away I felt abandoned. I haven't been to any family events since. Seeing that I'm in my first trimester its no biggie. I just don't know how or when I'll be able to tell anyone on my fathers side of the family. My mother doesn't keep on touch with them either. I honestly don't care if they don't find out until he or she is born. Any advice? Thanks
