So worried about a repeated miscarriage..

Kate
In October of this year, I had a miscarriage at just past 6 weeks. Now, I'm exactly 7 weeks pregnant again, and my husband and I are so happy to be pregnant. However, for the past four days I've had spotting/bleeding, not a huge amount, but consistently coming and going, and varying between pink and red with some cramping periodically as well. I've gone for blood work, a day and a half apart, and though my HCG didn't completely double, it did rise. I know this is a long post, and so many people post about the same thing. My doctor is trying to get me an ultrasound appointment for tomorrow to get some answers. I guess I'm just hoping someone will have a similar story that ended positively while I wait for more news!
