so my niece is 15 her and my sister ( her mother ) don’t get along very well and don’t have a great bond . she called me one

day telling me she had missed her period but doesn’t want to tell my sister , she asked me if she went to a clinic for pregnant women at 15 without her mother would they accept her if she just went with her boyfriend? I didn’t know what to tell her so im asking all my ladies , can she ?
