Ok so here is the deal. I am starting to get really worried about my pregnancy. I am 4 weeks and had an hcg blood test on thursday with a level of 900, and then had a repeat test on Saturday with a level of 1280. I know that they are supposed to double every 2 days but mine didn't what does this mean? My doc sent me for a repeat test today and I will get the results back tomorrow, but am totally freaking out that I am gonna lose this baby, any input?
