Missed miscarriage at 9 weeks 5 days 😢😢😢

This is my first miscarriage and was just curious about the timeline. We went feb 13th for our dating ultrasound, so excited to see our newest little peanut. But sadly it was just an empty sac😭😭😭. Any way got the confirmation February 14th it was a missed miscarriage, talked eith the doctor and made the choice to let everything happen naturally. Its now march 2nd. Ive had slight cramping here and there but nothing else. I feel like im torturing myself just waiting and waiting. But how long does it usually take for everything to happen? Is this normal for it to be this long? Thanks in advance. I would appreciate any advice you could give me.
