I have done my hcg on 23rd, it was 4853 miu/ml, after 48 hour it was 5703 miu/ml..is it normal..

Not normal should go: 2/3 in 48 hrs, you should check another one in 3 days as it doubles every 3 days, and your doc should be checking a Progesterone level also, if the next one doubles in 3 days which it may or may not then you need to follow it, and at 6 1/2 - 7 weeks should be able to see a fetus with a ht beat and right now should be able to see a sac in the uterus, if u do not see a sac, must r/o ectopic preg.
