I Am 3 Weeks Post Op From A Total Abdominal

I am 3 weeks post op from a total abdominal hysterectomy, yesterday I started a orangish watery discharge. Well today it's more like flooding out now. My Gyn. told me to be bed ridden for the rest of today to see if it stops. It hasn't it's gotten worse and the cramps are unbearable. It's freaking me out because all of this happened so quick for me I'm only 25 with 2 small children. Please tell me what's going on.
