Slow down!
Sweetheart, I want to you listen to personal stories of success, but stay aware of the fact of the other side. You're sharp and on the right track. It's great that you have concerns. Concieving a child is not the problem with the condition. Having a baby with an active contition poses high risk.
Why would people want to concieve or carry a baby knowing of infection??? Who knows! However, it sounds like you're the type to work with your doctor until you put a halt to this condition.
Don't be concerned that the meds are failing to work. Every body is different and your doctor must start at the bottom, so to speak. He'll fix it!
Don't reinfect! In the future, have your baby and be happy.
