Re: if my hcg level doesn't go up does that mean miscarriage
If it is any reassurance - hcg levels are only meant to double every 2 days for approximately the first 4 weeks of gestation. After that it is natural that the levels start to slow. As long as the levels are still rising you should try not to be too worried. If the levels were falling that would be a different matter.
Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree today.
