Having a Miscarriage?

Hey ladies,

I was thrilled and scared to find out I was pregnant about a week ago. Fast forward to Friday and I was bleeding. I should be about 5 weeks pregnant right now. I went to the ER yesterday because I was having cramping and bleeding. They did and ultrasound and did not see a sac and my HCG level is at 101. I have to go back for another Blood test in a couple of days. Is there any hope?
