What do I do

My friend is having a hard time she recently gave birth 5 weeks ago and she has two other children a toddler who is 4 and a baby who is 1 so far she has 3 children with a basically absent father. The father I may mention also has another girl pregnant she is due this week. Today she took a pregnancy test which showed a faint positive line. She is in denial and won’t accept that she is pregnant. I need some advice on what to do here
