Advice please..

I just went to the doctor last week and had a blood test which confirmed that I'm pregnant... But I called this morning and they said that they think my HCG levels are to low.. My last period was Jan 27th-31st... & I'm guessing the date I conceived was either the 13th, 14th, 16th, or 17th... So wouldn't that make me around 2 weeks? They said my HCG levels we're consistent to someone that is only just over a week or just under two weeks pregnant... But they said because of the date of my last period that they assume I should be further than that... Should I be worried that I'm loosing the baby? I'm freaking out. I'm supposed to go get more blood work done tomorrow... But had anyone else experienced this or anything like it? I've had the morning sickness and sore breasts... Any advice? I'm so worried.
