Please calm me down I’m so mad

My god child that I have guardianship over had secretly stopped taking her birth control and is now 15 and pregnant. I’m so clueless. I went back and looked at her recent Facebook posts for the past few months and she was sharing a lot of pictures of newborns and families and putting hearts as the caption. I should’ve caught on. i know she did it on purpose. Please give me encouragement. I’m going to make her get a job and care for and fully support the baby on her own
