Placenta Previa

Yasmin • Boy #1: 9/06/17 Boy #2: 6/14/23 Baby #3: EDD 12/27/24
I spent the day at the Hospital ER. Had some light bleeding and light cramps this morning. Baby and I are both great. But it turns out I have placenta previa. So now this is considered a high risk pregnancy. 
I'm 12 weeks along and I'm trying not to freak out, but I'm a FTM and this sounds scary to me. Any helpful advice or words of wisdom?
