OB question/advice needed

MissyP828

I had my first OB appointment last Thursday- baby measured about 5weeks & had blood work done. OB called me this morning, asking if I can come in TODAY for more blood work. Should I be panicking? They didn't seem too concerned when I arrived and I didn't even see the doctor, just the blood lady. They told me they are looking for my hormones to double and they should know the results tomorrow.  This is my first pregnancy, so I don't know what to expect.  I can't help but feel nervous.
