I started my period about 4 months ago. I feel horrible for not telling my mom. But I am super nervous and never say anything whenever I have an opportunity to tell her that I started. I have a twin sister who also started her period and I know that she told our mom without any issues but I just don’t know what to say or how to do it. So I’ve procrastinated and now I know I have to tell her but don’t know what to do. PLEASE HELP!
