what should I do??

Hughes • mommy of 4

my 16 year old sister in law told me she's pregnant...butt she's scared to tell her mom an her father an wants me to be the one to tell them but she wants me to wait until she is at school or over at her boyfriends. I tried to explain that she needed to be the one to tell them instead of them hearing it from me that it wasn't going to go well hearing it from a second party...i don't want to hear all the cussing a drama about it but ik if I don't tell them she'll just wait until she starts showing. she really scared to tell her dad mostly bc she's the baby of the family an her dad already said if she got pregnant her boyfriend would receive a a** whooping from hell....im currently pregnant with my 3rd child but I'm also grown an every thing...she doesn't work an asked if I'd take her to abort it...i can't bring myself to take her to do that I'm pregnant...what do i do?!?!
