Confused. . Help please

Alright ladies so I went to the doctor yesterday for my blood test after getting my positive hcg at home. They told me that I had to come back in a week for another one.. anyone had this happen to them..? Didn't really say much else either?? I'm pretty nervous we have been trying to get pregnant for about a year now. Any insight you have is truly appreciated. Thanks ladies and baby dust to all!!!
