Bleeding at 6 week

Mel

I’m six week pregnant and I having terrible cramps n bleeding I went in for an ultrasound this morning my doctor say my pregnancy is intact measuring 6 week there’s no heartbeat n it low in my uterus. He say there’s nothing tht I can do just take bed rest n called if I start bleeding more n passing anything. Did any of u guys bleed and still went in to have a normal pregnancy?
