Hcg levels

Ashley
Can someone give me some insight into what their levels are or were at 4 weeks 3 days?  I had my levels checked yesterday and mine were just at 79. My doctor said that could be normal but to have them repeated tomorrow. I'm so scared I'm going to lose this baby. This is my 4th pregnancy. I have a son that is 4 and the other two pregnancies ended in miscarriage within the first few weeks.
