Gushes during nursing/activity

I'm 11 days PP and when I'm just sitting around holding baby I am having very watery light red discharge and a few times over the past few days since its lightened up I'm having these gushes of blood almost like I'm peeing myself. I will fill a pad and the toilet in a matter of seconds, then goes back to nothing! It's very scary and definitely nerve wracking. Anyone else ever have this? ob said stop doing housework, errands, ect, come in if it happens to two pads in a row or for two hours in a row, and that I need to just do nothing until it stops but this is my fourth and I've never had this happen.
