You need to test yourself as Stephen described, with number 4. meaning doing ultrasound and Fibroscan of your liver.
Only after you do all of those 4 points you can have an idea of the state of your hepatitis virus and the state of your liver.
For someone to be classified as an "inactive carrier" he needs to maintain an inactive virus status for entire year (which isn't the case for most of hep b carriers).
There are good medications nowadays, which if needed one takes in order to stop the progression of the disease. The important thing is to monitor the disease (like every 6 months) in order to make sure hepatitis virus doesn't do major damage to your liver which could lead to liver failure and cancer.
Don't worry to much, but make sure you follow it...
Some Hepatitis B patients maybe in an "inactive" phase, and immediate treatment is not necessary, the patients can just observe and be monitored. The term "healthy carrier" is not used anymore as it may give the wrong impression.
In order to know whether you need treatment or not, we need more information from you, such as:
1. Liver function tests result (e.g. ALT)
2. serology test results (e.g. HBeAg status)
3. Viral load (hbvdna)
4. history.
As for your wife, the baby must receive the first dose of the Hepatitis B vaccine at birth. Your wife should also be tested for Hepatitis B (her HbsAg status). If she also has Hepatitis B, the baby must also receive HBIG at birth to prevent vertical transmission of Hepatitis B infection. If necessary, your wife may also need to take Tenofovir at the third trimester. Talk to your wife's doctor.
