Friend tricking BF into getting her pregnant

My "friend" currently is in the pill and thinking about stopping, or maybe already did, but they also use the pull out method. She recently told me she she wanted a baby and when he would cum on her belly, she would grab it and put it into herself. I told her what I thought about this and how wrong it is. She just told me this morning she's pregnant. I am just disgusted in her that she would trick him into this. I told her I will not talk to her anymore because it's terrible. I am not going to tell the BF anything as it's not really my business. I just needed to tell someone cause it's eating me alive! Ugh people are sick.
