Advice??

Alice • I’m just a 14 year old sexual assault victim so don’t judge

Ok so I’m not really sure what to do I’m 14 and just found out I’m pregnant (I’ll be 15 when the baby is born), we live less than a block from planned parenthood and my mom’s a workaholic so she’s never home, I went for a ultrasound yesterday and now I need to tell my mom, I’m not sure how to tell her, and tips or advice?
