Late Postpartum Hemorrhage??

What are the odds of hemorrhaging twice from the same birth?? Had a PPH a few hours after birth and I have been scared to death that it is going to happen again. I will be 2 weeks postpartum tomorrow (had DD on 4/12 ). My doctor said not to worry, he didn’t think it would happen again and to relax and take care of myself. But I haven’t been able to go a day without freaking out and being scared.
