I am a little over 4 weeks pregnant. my hcg on friday was 825 and by monday it was 3800. this seems high and fast rising. is this normal?

WHAT DID YOUR OB SAY: You should have already asked your ob! the beta is supposed at least double every 3 days if the preg. Is normal and they should have also drawn a Progesterone level which can indicate if the preg is normal, so it seems that yours is normal but depends what the progeserone level is and at 3800 u should be able to see a sac in the uterus will be too soon to see a htbeat which can be seen- 6 1/2.
