I was diagnosed with chronic hep b 5 years ago

. I had an acute episode when diagnosed, but since then I have been in remission and the damage to my liver has been very minimal, thanks, in part, to avoiding alcohol, as well as medications that can damage the liver.
I recently had gastric bypass surgery which, was a risk, but not having it was a death sentence. Everything is going well, but due to the rapid weight loss, it causes a sort of hyper fertility. My husband and I have always used condoms and always will, but, getting pregnant right now would be very dangerous for me and a baby. So, I want to try to find something that I can pair up with the condom.
Does anyone take or know what kind of birth control is recommended. I talked to my doctor about the depo-provera shots, but they aren't recommended for those with liver disease. So I did more research and it seems that any kind of birth control medication has the same warning.
I don't want to take a chance getting pregnant, and I know condoms can fail. Plus, I don't think my husband will go for abstinence.
I appreciate any and all responses!
