Placenta previa

Br

Has anyone ever had this early on? I’m beyond nervous because I’m a high risk naturally due to having type 1 diabetes. And this morning I woke up with spotting and heavy cramping. I called the OB and he got me in right away. He claims my placenta is way too low and the bleeding is coming from the placenta. He wants to put me on bed rest but I’m only 16 weeks and 2 days. I’m worried about the baby..
