(but i was low with my son too and he lived). my levels were low with the last one but we saw a heart beat before i lost it. anyways...im pregant again i didnt even get a period. my level on monday was low like 462? but to day it had more than doubled...almost tripled he said. he wants to see me in 2 weeks for an u/s. this is good right?
