Best Answer: A non reactive HBsAg (hepatitis B surface antiGEN) tells you nothing about your immunity to hepatitis B, only that you don't currently have the infection. If you are trying to work out if you need hep B vaccination you should check the levels of anti-HBs (hepatitis B surface antiBODY).
You should call the doctor now to make an appointment, they generally dont get you in until your around 8 weeks pregnant... up until your about 7 months pregnant you will only go to the doctor once a month, after your seventh month you will start going about every 2 weeks... when you get around 36 weeks you will start going every week.

You'll be hopping and skipping to this doctor's appointment -- most women agree that an ultrasound is the one prenatal test they enjoy. An ultrasound is a painless diagnostic test that relies on sound waves, and most women will have at least one during pregnancy. Your first ultrasound will typically be done between 18 and 20 weeks, but you may have one before 12 weeks to confirm your due date.
