I have done IVF, my first blood test (day 15) HCG level was 25, than they ask me to test it again 2 days later, (it went up to 61) then another test on the 20day (hcg went up to 126). They call me up and say because the number was so low at first that it might be ectopic pregancy, they want me to go in next week friday for utral sound. I am very worry, and depressed. They did not say I am pregnant or not, they just say I don't konw until the utral sound. They even said it might just be a empty sack. They don't know.
